When I make templete mods, I always ask myself. "If I were surfing this board, would I enjoy this? would it make it eassier for me?". You should never release a mod becaouse it looks cool and was just hard to make. If oit will make things harder for a user, caouse problems, ect. Then dont release it.
but the main thing is like I said above think about if you were surfing the board if you would like to see it. If you would. chances are others will to :)
Remember though that one person's trash is another's treasure (i.e., you might not like the mod but somebody else could :))
In that case, release whatever you want just make it useful in some way to the user. Even if you hate it.
