Sometimes you want an event to change or an audio to change once it gets to the end of a current music track. Right now, you have to judge how long the audio track is and try to enter a wait command that will correspond. If this could be more automated, it'd be great. There are a few situations where I see this can help somebody:
1. If you want the audio in battle to change once one track ends.
2. Ending credits
3. A cutscene that plays a song
4. For scripts that include title screen events, you could have it so that once the title screen music ends a secret prologue will play before going back to the title screen.
Speaking of title screens, the ability to create events with the title page without resorting to a script would be nice. Also, a set of stock title resources (cursors, word art for New Game, Load, and Quit), would be a nice touch.
Edit:
This may be possible with Ace, but I haven't used it much yet. Anyways, working with VX, it dawned on me how limited status effects alterations were when dealing with equipment, items, and skills.
Weapons allow you to add a state when you attack, but it doesn't allow you to resist or change states.
Armor allows you to resist, but not add or change.
Items and Skills lets you change states, but not add or resist.
It'd be nice if you had more flexibility in adding, resisting, and changing regardless if it's a Weapon, Armor, Item, or Skill.
Again, with formulas this may be more practical with Ace, but since I've been using VX for awhile, I figured it's worth a mention just in case.
