Customize file and folder names in sidebar (project view)?

[rainer14]

Is there a way to customize the displayed filename?

Then I could e.g. hide prefixes of filenames, enabling a workaround to display files in any order. Related [1].

Or this could be used to hide file extensions, to unclutter the sidebar.

Sidebar : folders and files order

Hi everyone. I think it would be very very usefull to have the sidebar displaying the folders and files NOT sorted by folders/files nature (means not like it is now : the folders on top than the files). Thank you.
