                OS: All

A few comments on the recently added timers/timeouts.

— The recently added "disable while typing" timer. —

It's a bit difficult to determine what is "typing" and what is not. Currently
it triggers on all non-modifier key events – which means, I lose the touchpad
every time I switch between programs with Alt+Tab, or terminal tabs with
Alt+1/2/3…, or browser tabs with Ctrl+Tab, or select files with Ctrl+A...

Well, in short, it has many false positives. I think it could at least exclude
the Tab key, and/or keypresses when a modifier key is being held? That would
take care of many false-positives with Ctrl/Alt/Super shortcut keys.

Anyway, I see the changelog has "the feature is currently enabled for all
touchpads but will be reduced in the future to only apply to touchpads where
finger width or pressure data is unreliable". So I'll just wait for that. I'm
fine with having to add hwdb entries or something.

— The drag timeout (recently increased to 500 ms). —

I know it can be cancelled with a tap, and I'm trying to get used to that, but
it still feels as if the driver is buggy (or lagging like hell).

I can see the timeout being useful with slow cursor speeds, when one needs
several swipes to drag something across the screen. But it's something that
varies greatly between touchpads and AccelSpeed settings. In my case, it's
mostly useless even with AccelSpeed of 0.0, and outright annoying with 1.0. So
if the speed is adjustable, I think this timeout should be as well?
