Comment (by leavengood):
I'm pretty sure we do the diagonal "triangle" movement tracking shown in
that blog post, but I suspect the missing element is time. At some point
after the user stops moving the mouse the diagonal sub-menu tracking
should give up and the current hovered-over item should be selected.
The only issue in trying to fix this is our menu-tracking code is quite
complicated and hard-to-change. I've seriously considered trying to sit
down and completely redo it, using a more object-oriented approach, but
that is hard due to lack of time and of course the fact that our current
menu code is already so complicated one would need a very good test suite
to make sure nothing is broken in a redesign.
Some have suggested just waiting until after R1 is released to do a menu
redesign as part of a new menu API (as supposedly part of the current
difficulty is due to the BeOS menu classes design), but I don't think that
is a very good excuse.
As for this ticket: it would be cool if Haiku could be one of the only
modern operating systems to have menus actually work properly like they
did in the original Mac OS.
