Make Content browser Source Panels being rearrangable?

Okay… I searched the Editor Prefs and stuff… but couldn´t find an answer…

The Content Browser of UE5 is made of diverse Objects… My target here is the very left Panel, the Source Panel.
The Objects inside are the Favorites, the Project Folder Hierarchy and the Collections.

My Problem here is, that this Panel is way too small to have all 3 of those sub-panels being arranged vertically.

Question:
Is there a way to have the Folder Hierarchy being a list on its own on the very left side, while collections and favorites are separated lists, too… and all 3 arranged horizontally? It would give the lists more vertical space and makes everything more clear.

If not being implemented yet… can we please get that?
I´m working here with lists… sometimes only showing 3–4 items and huge scrollbars… until I stretch the content browser in its height… covering the scene view and details panel…etc
