Hi Michiel, You can use every tool you prefer in my opinion. BTW for icons in tangerine I'd like to have the "source file" in bzr as well (like we do for tango-icon-theme and for g-i-t upstream) and those source file should be either in xcf (gimp format) or svg, since you cannot force people to use proprietary tools (which costs money, and usually lots of) while you can "force" them to use oss since it's free. So my take is that you can work with whatever tool you like but if you need to concurrently work on something you should provide the files in an oss friendly format. Ciao Lapo
