Two simple requests for what would be rather nifty software. First of all, a (very) basic spreadsheet application. Just adding stuff into cells, and some pretty basic formulas (SUM being the key one). I could see it getting used a lot. The second one, which I would love even more (though who knows how much demand there is for it) would be some kind of tournament organiser. You can enter the names of players and it'll auto-generate a single elimination, double elimination, or league tournament and take all the hassle out of working it out for yourself.
