This is one of those things that I might have done differently if I were starting BandHelper over again, but it could be quite disruptive to change now. The current module names include Repertoire, Schedule and Finance. Would BandHelper be more inviting if those had "friendlier" names like Music, Calendar and Money?
I tend to think the current names are more precise and these names might mislead people about the functionality. For example, people might think "Music" functions like their iTunes library, or "Finance" accepts payments for merch sales. But I'm curious to hear your thoughts about it.
