Hello Toufiq, if i add a new Section, hit the "+" Button or "Add Elements" Button i can add the Addon i want to have in that Section.

If the Layers window is opened no Addon can be added anymore. Even if i close the Layers window again, i cannot add any Addon until the page is reloaded again.

This behaviour started after you made the Layers window movable.
Video to reproduce is in Hidden Content.
