While I was working on the next tutorial I found myself implementing a side panel over and over. That side panel had a button to shrink or expand it and is meant to hold a few settings to change the overall behavior of what I wanted to show within the tutorial.
In order to avoid having to continue re-implementing the side panel I decided to create a generic one and turn it into an addon. And here it is!
As usual, you can find the addon itself on my Github repository
A dedicated tutorial for it can be found here.
A quick preview of this Control in action is shown bellow:
