As shown in the following image I can close the problem tab pane by clicking on the X symbol at the end. When the extension is enabled, it opens the pane, whenever I hover on any part of the code, which is a bit annoying as, not all the time we want the pane to be open.

If somebody wants it, they could manually open the pane and hover on the code.
