One thing occurred to Animus01 (A PureZC Member), and hopefully, it's easy to implement: Quest video recording. Emulators have a game recording, so why not the same option for our quests?
Things it can be useful for:
1) Showing off bugs and glitches better
2) Giving other people in PureZC, AGN, and other forums assistance in quests (ex. going through a dungeon, fighting a boss, etc.)
3) Showing off, period. Make your custom boss battle known to all!
4) Time attack in dungeons.
5) Reveal secrets to other questers easily.
6) Make videos as sorta trailers for upcoming quests (maybe open with Windows Movie Maker for this one).
So, basically, that's pretty much it. If it's already implemented, let me know. Just don't have several people reply saying the exact same thing if this occurs. Just one can tell me if it's already implemented.
