1: Lua Script support
I'm just now starting to learn lua scripting, and would be a very cool addition to Construct 3 so people don't have to do javascript, which in my opinion is kinda harder.
2: Set field of view action
There should be an action for events that sets the field of view.
Example: Minecraft has options to set the field of view to your liking.
3: More 3D support OR Construct 3D
Yes, I know there's already a 3D platformer in the example browser, but it's kind of buggy. What if there was a better type of this, which could possibly lead to a 3D version of Construct?
