After a few months of using this, there are a few features that would be extremely helpful...

-A button that would list what members are not on the list, but ARE in the party. This takes a long time to verify every time if you don't raid with the same set team every day (and I always seem to miss someone).
-A way to rename lists
-A way to add players to a list named something you want, not just the prefix. (So instead of "25Man - Raid", you could just have "25Man", that way I can add the " - Raid" myself if I want still).
- Make an option so that players can not change their position by re-rolling while the list is "Active".  When we ask a new entry to roll into the list, someone is always not paying attention and rerolls (or if I mistakenly think they aren't in the list) it moves them.
