I have been away for a few days, so I couldn't answer your questions, but it seems that you managed very well in answering them yourself
I am currently experimenting with a way to get the 'views' in the Home screen configurable, so that it would be easy to add new views (or hide existing onces from the Home screen). I currently have an Application-View icon and an Installation Files-icon on the emulator, so creating new views is not that difficult. I am now thinking on how to make it user configurable.
I will also need some way to modify the tags of a document, without breaking the current behaviour.
I currently have my holidays, so I have some more time then I would normal have to play with the DR. (I will also go to Barcelona for a few days, so I do not spend all my days behind a computer and DR.)
