Actual results: There was rarely a visual clue to where the cursor currently is. Only the select items could be used as orientation. Expected results: I would expect a dotted border to indicate the current position. Or a different background colour or something similar. I know from Nightly, that the whole settings dialog shall be integrated into the AddOns view, but want to highlight this issue anyway.
