Some ideas:

*The "manual" button should open more file types, like .DOC.

*Also the specified name of the manual's temporary folder should be separate from the name of the mod that appears in the launcher title bar. (CannisRules: Balance of Power kills the manual, since can't have ":" in a folder/filename. No biggie but this drove me absolutely crazy for a half hour)

*The "launcher" section should accept the option for a custom program icon. Nice for the user who maintains a number of XMC/L-launched mods, and nice for the modder with an ego ;)

*Button locations should be map-able.

*If RA2/YR should crash, it would be nice if the launcher didn't go away too. Then the 'fail to delete the mod files when the game crashes' problem could possibly be avoided.
