Current way to rename script files is somewhat clumsy - you need to switch to Reforger Workbench window, find file there and then rename it.
Considering that common IDEs (Visual Studio, IDEA, VSCode etc) have the ability to manipulate files behind the code right from the solution explorer, it would be good if it would be allowed to be done from Script Editor, especially since we already have the ability to remove scripts from the Script Editor solution explorer.
