Thanks for your input on the issue, Gunars! You are absolutely right about the File menu being not very usable. However I doubt that having two tab rows one below the other would be a much better solution. Probably making sections vertical or moving them to the botton could be a better alternative. So still need to ponder on it..
Thanks for the input. I've recorded this as a bug and scheduled the fix for version 2.6.
