True. Each user places them as he likes, but most will end with lot of
dialogs open (the wm's shade function is your friend, at least mine).

I use PCs, I have tested wheel mouses... no thanks. It is just a way to
convert a useful button into "three" unuseful ones. Software that requires
three buttons is a pain with this "cool" mouse, at least for me, becuase the
middle button is a small bastard that moves forward and back when it wants.

I am still trying to see a situation where the wheel does something that
middle button can not. Scroll? Click, drag a bit and scroll in any dir, the
more you drag the faster it goes (some software does that, others do as
Gimp, which is not bad either). Zoom? The same as scroll. Combination zoom /
pan? Key your hand near ctrl key (or any other modifier). 3D manipulation?
Middle and drag gives you a two continue axis precise control.

Well, forget all the ranting. I just want to say that three buttons is cool:
MB1 for action, MB2 for view (zoom, pan, etc), MB3 for menu.

Keybindings, typing fingers are faster than mouse. I use 12345 keys plus the
key near 1 and versions with Ctrl (12345 zoom in to fixed ratio, ctrl+12345
out, extra key in / out in small steps).

One nav window, like one L&C, is a good idea. With auto on / off and drop
down menu to select like L&C (no icon needed here, I guess).

My two Ecent, if someday we use them. ;]
