Re question 2 there is a problem there, it is to do with the ur driver apparently, if you go back to the previous driver it doesn’t ask at startup. Re no 3, go into the plugin manager, there’s a little cog wheel in there somewhere for settings, you can delete and add new paths there. Re no 2, not sure here but I know that right clicking some plugins (guitar rig in my case) title bar one can click or untick always on top there.
