MiroJ: just read the thread a little bit and you have your answers. The questions you ask are answered in page 1 and 2, if you have any more problems just read the thread more.
Edit: Here a little step-by-step for disabling hotkeys: install robbieone.apk linked to earlier (FolioWidget). Install button saviour from Market.
In button saviour:
- Enable Long Click Trigger
- Disable Vibration Feedback
- Change Auto-Hide to 1 sec
- Change Trigger Icon Transparancy to 0
- Change Sidebar Position to 0
Then after that, add the Folio Widget to one of your homescreens where it doesn't bug you. Click on the widget and change Key sensibility to 0 (you might have to view this in portrait mode since the menus are a bit big).
Pretty much as good as it can get solution for no softkeys.
Really loving this ROM despite a few little problems
It's really good for what I use my tablet for (reading Manga, browsing web).
