Just learned something pretty cool about the FileSystem in Godot 4. If you right click on a file in the file system.... in the menu that pops up... you can select "Set Folder Color"... and from there select a highlight color for the file(s).
This really cleans up the files in the folders and seems to help your work flow in the process. I personally "CTRL+drag" a lot of files in from the docker.... and this has helped me select the proper file more than once now.
Figured someone else may appreciate this TID-BIT.
