Here's an unrelated feature I've just added in: any file which includes the ID number of a thing can instead use the internal name of that thing instead. This applies to:
The only downside is that all the files would need to be renamed first to include internal names rather than ID numbers, which is a big task. Should I do this (for Pokémon only)? Bear in mind there's over 3300 battler sprites alone which would need renaming, plus at least 649 of each other kind of file. It'd help if I had some program which could automatically rename bunches of files - does anyone know of any?
One other downside is that it'd be harder to spot missing files, since you couldn't just scan a list of files to find a missing number. I don't know how useful it is to be able to quickly scan through lists of numbers to find gaps, compared to the usefulness of freely rearranging the National Dex.
