I think it would be easier and more useful if autosaved replays were to include a category for mods. (ex. [Secret]Mysteryvs[Urban]Erth1337-666.aik.rpl)
Aik is short for aikido.
More abbreviations would be like:
jud>judo
wsh>wushu
xpr>xspar
nnj>ninjutsu
This would be beneficial because it would be a lot easier to distinguish which mod you used, and which replay shows it(the mod you want to find the replay for).
