Jump Desktop V8.5.2 - keyboard operability lack and fails

Please remedy the widespread non-operability by keyboard. .g. menu bar, the unlabelled front page slider, the username menu, "More options..." https://i.imgur.com/UJT1LuU.png.

Please fix the TAB order failures of the existing partial keyboard operability e.g. preventing entering, and switching tabs in, Network Settings and Keyboard & Mouse Settings (below) by keyboard.

Thanks.
