It's from Undo History, just save and go out of editor once in a while / a simple restart will reset this.

This is why there's an option in the options menu to disable undos. It should fix all of your memory problems at the cost of, well, not being able to undo.

Yeah, but sometimes you do something wrong, like moving a slider to a wrong place and you want it back, but you don't know where it is, which is why I'd say it should save up to a max of 10 undos (Shall I make feature request for this, to set the maximum amount of undos it'll save to prevent lag in the editor?)

That'd probably be a good idea. Even 10 seems perfectly fine for most use cases, though.

It should only be storing at max 20 states unless something is broken and causing it to exceed that. In any case testplaying clears the undo states. If this does not lower the memory usage then there is something wrong with the disposal of undo states if this problem is actually related to undo states and not something else related to marathon maps.

Nope, i think it's fine undo-ing a hundred times than what you need. And i don't think the richies, like me, need this FR killer like the other ones(e.g. move notes with arrow keys/hide interface on replays/etc....).

btw, I'm using the latest Samsung Simple 21.5 Monitor that run programs particularly smoother, by then, no single lag hell when i undo notes a lot. And yeah, richies doesn't need that to rage hard just for the undos. One more thing..... I won't agree with this, if i talk sht again(?)

No? Then fine, we'll see in the future days. If the crowd of mappers would tell about this request is positive, "gg". If negative, "fuufuffffufuufuuu kill it pls".
