If I have a tab open called “foo.txt”, and in the sidebar I right-click -> Rename and change the filename to “bar.txt”, the filename changes in the sidebar but not in the currently open tab.
This creates a very inefficient workflow because now when I close the old “foo.txt” tab and it prompts me to save, it creates a new file called “foo.txt”. I then have to delete “bar.txt” and rename “foo.txt” to “bar.txt” in the sidebar, making sure any related tabs are closed.
