Quality setting is good for saving disabled icons (15-20% quality images are looking normally). Who will scan each pixel of disabled icon, and stop playing map only because quality is horrible? Palette size reduction also would be useful for (again) disabled icons, or icons with several general colors (e.g. icons for weapons from TcX). Less palette size => less blp size.
Well, if you think my ideas are bad, give me a good ones, please.
About "cohaders", it was some type of joke, but I really know at least 1 coder (NETRAT) which would use dll for his own program.
By the way, Tide-Arc going to buy second computer (pc-based, not mac), install windows and use this program =))
