I've been using Ultimate++ for a while now, and I don't know how I overlooked this, but I just noticed the italicized font for the 'mate' part of Ultimate++ ! (at least noticed it ENOUGH to actually think about it.) What was the reasoning for this? Was the 'mate' meant to signify 'friend'?
Ehm, AFAIK, nothing. Just artistic license.
BTW, I think it is time for the logo redesign. Current logo exists for too long now...
In the process, I would also make a "silent" project name transition, renaming platform to just "U++".
