I doubt Badspot is going to implement this in any way.
The current event system still works great and it has already many addons.
Redoing the event system means redoing all those addons.
It also means redoing all and every save with events.
So nope, that is not going to happen.
Sure, the event system needs an update.
A previous thread had some neat ideas expanding on the current system.
Events are used to quickly add some small programming code into a save.
If you want to go more complex, make a script.
plus I suck at scripting and programming unless it's something visual or tangible, but maybe that's just me.
"no syntax necessary" is what I like to say. Just logic.
Well that is your problem, not the problem of the community or Badspot.
Make an addon that does all this and use it yourself.
