[Bf-committers] Pupmenu conventions. (Was: CVScommit:blender/source/blender/src edit.c)
Thu, 9 Oct 2003 17:08:49 +0200
I am not against changing order in menus.
Menus only have to be logically structured, and if possible remain
compatible with older versions.
In the Snap Menu, which was a SNAP CURSOR menu, the new 'selected to
centre' option can logically and consistantly put to the end, also to
reward the old convention. It was even doubtful if the option belonged
Such decisions, as I said before, can just be looked at at a per case
base. And I doubt there are many cases we should reward old conventions.
