It would be nice to have a button to delete the content of the root directory (check screenshot) and also rename it? I am not even that clear with the purpose of the root folder, could you please explain?
Hi Da_v_id , thanks for your suggestion, we will obviously think of it for further development. 
my case is very specific, I am testing the different way to import endpoints, and would like to quickly cleanup the root to remove all the imported controller
Click on the root folder, then go to the “Endpoints” in the right-side directory settings for batch operations on project endpoints. You can refer to: Batch endpoint management - Apidog Docs
