There are a few things we need to improve level quality. There are already a large amount of possibilities with the current ones, however these additions would be nice.

Random Input Trigger:
Already exists in a mod, and can be done in the base game. The base game version has some drawbacks, however, requiring an enemy to trigger the triggers, an animation/movegroup to move the triggers, and platform outside of the map. On top of this, a trigger that doesn't only trigger once activates five times every animation tick.

Proximity Trigger:
Activates when a character is a certain distance away from another character. This would come quite in handy if you wanted to create custom attack animations.

Character Killed By X Trigger:
This trigger can have two characters, or a character and a hazard assigned to it. when the first character kills the second character, the trigger activates. this also happens if the selected character is killed by the selected hazard type.

If Trigger:
Would trigger upon certain events, such as a dash, animation, another trigger triggering, ect.

Title Input Trigger
This trigger would be almost identical to the player use key trigger, but display text on the top, middle, or bottom of the screen. Would be useful for both cinematic, and custom abilities.

Anyone else have ideas, because I'm running out of options here!
