In Kate, when choosing Sessions -> Manage Sessions, I had initially two sessions in the according popup. After deleting one (the Default session by mistake), the remaining one could not be deleted, because the Delete button gets disabled for the last session. Reproducible: Always Steps to Reproduce: 1. Open Kate 2. Create at least two sessions 3. In Sessions -> Manage Sessions delete the first one, then try to delete the second (last) one Actual Results: The Delete button gets disabled before you can delete the last session Expected Results: The Delete button should get disabled after deleting the last session.
Even more, I found that if I create a New session without actually saving it and then open the Manage Sessions popup the last session displayed there can be deleted. In this state I still don't see there my new session actually opened.
This is by design: - The currently opened session cannot be deleted. - When you have a unnamed (=anonymous) session, you are essentially not in a session, and therefore, this temporary session is not displayed. Closing as wont-fix for now :-)
