{% update date="2024-09-09" %}

## <mark style="color:$success;">**V.2.5**</mark>

* This plugin now features an “Multi Window Tick Event” which you can assign in your Multi Window widget to have a tick event in your widgets. It ticks every 0.01 seconds.
* The detection of size changes and such stuff is way faster now
* New “Quit Game If This Window Closes” boolean input
* Man idk… I removed the **EDITOR** subsystem as it just caused plenty of issues, including crashes and more. It wasn’t really used by anyone anyways but if you were one out of like two people who used it, I would suggest you to just use Editor Utility Widgets N' Stuff. Way easier to handle anyways.
