LinguaX: a native, lightweight mouse enhancer for macOS (smooth scrolling + per-app button mapping, ~10MB)

Honestly Mac Mouse Fix is great, I'd recommend it without hesitation if smooth scrolling , button mapping and the drag gestures are what you need. It's native, open source, and basically free (v2 is free, v3 is a one time couple of bucks after the trial). For a lot of people it's the right pick and I won't pretend otherwise. Where LinguaX actually differs: - Direct Logitech hardware control : it adjusts DPI and toggles SmartShift (free spin vs ratchet wheel) in app, with no Logi Options . MMF doesn't do that, and on some Logitech mice it can't even see all the buttons (their own site says so). - Bonus stuff a bit beyond a pure mouse tool: per app input source (keyboard language) switching, and push to talk dictation from a button. So if you just want great scrolling and gestures, MMF is excellent and cheaper. If the Logitech DPI/SmartShift side or those extras matter to you, that's the gap LinguaX fills. Both have trials, so honestly try both.

totally fair! i went one-time lifetime instead of a subscription on purpose, so it's a single payment covering 3 devices with no monthly fee. felt that beats nickel and diming people every month. and the trial's full featured, so no rush to decide. appreciate the honest take!

Honest answer on both. The scroll sensitivity fine tuning is the part i'd genuinely point you to. It has a tunable smooth scrolling curve, so if that's exactly what you fight with on BetterMouse, the trial is worth it for that alone. The hold side button and scroll to zoom though, i have to be straight: it's not in there yet. BetterMouse does that by translating your scroll into zoom keystrokes, and i haven't built that specific scroll to zoom action. You can bind a button to a Zoom In or Zoom Out step, but not the smooth hold and scroll page zoom you're describing. Genuinely good request and i've noted it. Didn't want to sell you on something that isn't there.

awesome, would love to hear how it goes! the Safari and Chrome thing is the classic hard case, browsers do a lot of their own scroll handling so smoothing tools often skip them or end up fighting them. LinguaX lets you flip smoothing on or off per app, so you can force it on specifically for Safari and Chrome and see if it feels right. genuinely curious how it does there with your Lift, that's the exact case I obsess over. lmk!

totally hear you. i went one time lifetime (3 devices, no subscription) instead of a recurring fee, but i get it's more than the free or cheap options. honestly if you just need smooth scroll and button mapping, Mos or Mac Mouse Fix do that well for free or a couple bucks. the price is really for the Logitech DPI and SmartShift control and the extras on top of that. the 30 day trial is full featured though, so you can see if it's worth it for your setup before paying. appreciate the honest feedback!

For most stuff, yeah. It covers the core of what people actually use Options for: DPI, SmartShift (free spin vs ratchet wheel), button and gesture mapping, smooth scrolling, all per app and with no account or background bloat. Honest exceptions: it doesn't do Flow (controlling multiple computers from one mouse), and it can't push firmware updates to the mouse, so for those two you'd still keep Options around or fire it up once in a while. But for day to day mouse behavior it's built to replace it. What do you mainly use Options+ for? happy to tell you straight whether it covers your case.

Honest answer: not true chords like SteerMouse, where two buttons pressed together fire a third action. That isn't in there right now. What it does have: clicks with keyboard modifiers and click count, long press, drag based gestures, and a modifier hold where one button acts as Cmd, Shift and so on, so you can combine it with another button or the scroll wheel. So some combo style stuff works, just not arbitrary two button chords. If that's a dealbreaker, SteerMouse is genuinely better for that specific feature. But i'd love to hear what chord you'd actually want, it's the kind of thing i'd consider adding.

thanks.

The DPI and SmartShift control goes through Logitech's standard HID++ features, so any mouse that exposes them can work in principle. In practice it's been built and tested mostly around the MX Master and MX Anywhere line so far, which is exactly why your point about a clear support list is right. I'm going to publish a fully supported, partially supported, and not yet tested matrix.

Good news, you probably don't need the workaround anymore. Recent macOS added a toggle for exactly this. Go to System Settings, Mouse, then click Advanced, and there's a Pointer Acceleration toggle in there. Turn it off and it disables the acceleration curve directly. One heads up: with it off the cursor can feel slow, so you may still want to nudge the tracking speed or your DPI up a bit, but you lose the acceleration without the whole sensitivity dance. It's tucked under Advanced so it's easy to miss, lots of people don't know it's there.

Straight answer, i haven't tested a Naga v2 Pro specifically so i won't promise. A few honest expectations though. Smooth scrolling and the standard buttons (left, right, middle, back, forward, tilt) work at the system level regardless of brand, so those should be fine on any Razer mouse. The 12 button side grid is the part i'd be careful about. On the Naga those keys often enumerate as keyboard keypresses rather than distinct mouse buttons, especially on macOS where Razer's own software support is limited, and LinguaX keys off mouse button events. So some or all of the 12 may not show up as mappable mouse buttons. The deeper hardware control like DPI is also Logitech specific right now, so you wouldn't get that part on Razer. If you're up for the trial, the Naga is a great test case and i'd genuinely like to know how many of the 12 it picks up as mappable. That tells me whether proper Razer support is worth building.

dev here. honest answer: pointer speed yeah, there's a per-device speed slider and it saves per physical mouse, so each mouse remembers its own setting. acceleration is where i'll be straight with you: LinguaX adjusts per-device pointer speed but it doesn't have a full accel-curve editor or a hard "kill acceleration" toggle. if a flat zero-accel feel is the specific thing you've been chasing, LinearMouse nails that and it's free, no shame in using it just for that. where LinguaX is actually different: on Logitech mice you can set the hardware DPI right in the app (no Logi Options), which gets you precise sensitivity at the hardware level, plus per-app smooth scroll and button mapping.
