As it seems we're switching to SVG, I'm wondering if it's possible to
suggest already existing icon sets like the ones coming out of the Tango
Project? The Tango set is growing, and I think it'll fit BeOS well.
Tango seems to have some great guidelines also.
Whatever we may end up with, I want to express the importance of a unified look, and if it's going to be possible to change icon sets (like it is in Lotz' Tracker version IIRC), it's important that these changes are system wide. Maybe this is further ahead in time though.
