This may not be exactly relevant, but here goes.
Mouse drivers need more precise control of very small movements (i.e.
1-2 pixels). This is evident when one tries to make a diagram in
OpenOffice, or grab the edge of a box in Gimp to tweak its size. I think
it is possible to improve the fine control to make such operations
easier and faster.
The method: when mouse speed slows down to a few pixels / second,
increase the ratio of mouse steps to pixel steps. Normally this is 1:1,
but it could become 2:1 or 3:1 as the speed goes down. This is the
reverse of the acceleration table built into mouse drivers, whereby the
ratio goes in the other direction as the mouse speed increases.
This would also be a help for persons with shakey hands doing routine
things, like grabbing the edge of a window to pull it out.
There is a "sensitivity" asjustment in Gnome mouse preferences, but it
seems to do nothing. Am I missing something?
