Improve UI/UX for mobile

[judeibe]

I have been drawing up some UI flows in my down time. This is some of what I came up with.

The unfiled items issue is something that has come up on the forum -- I think I'll need to add that no matter what, even though it would require modifying the current system to move away from a basic CursorAdapter, since Unfiled isn't a collection per se, and won't be returned by the collections query.

The child collections logic needs to support arbitrary depth, which is difficult with a more classical tree approach. Is the current activity swapping confusing?

The change to the initial activity I had been considering was adding collection/library stats, last sync, etc. Also an advanced search interface.

And a little thing-- what are the three boxes next to the search icon in the action bar?

Those 3 dots are are the symbol for menu in ice cream sandwich. The plus is
to add items. In context to where you are and. The magnifying glass is
search, since ics no longer has a dedicated search button

I think this goes along with an improved tablet version.
