Google Drive app on Nexus 7 doesn't allow offline editing Okay, so I have a problem. 
I have a Nexus 7 (rooted, unlocked bootloader, but no other changes to the system).
I have a few google documents (native gdoc format, I'm the owner) that I'd like to edit in my spare, off-the-net time. 

The problem is, when I select 'make available offline' in the application, the document appears in the offline tab, and I can edit it as long as I'm connected to a network. When I disconnect, wham, offline documents are set into read-only mode, I can select text, but I can't do anything else (also, there's that blue-ish bar on the top with ios-like "all docs" button).

So, what's going on? I really need to be able to edit some documents when I don't have an internet access.
From the looks of it, at this point, marking something available offline only allows you to read it offline when using a mobile device (Source). However, you can edit and write files offline if you are using a computer or device running Chrome or Chrome OS. I'm sure at some point Google will allow editing offline, especially for tablets, but at this point, I am pretty sure that you can online view files offline. Sorry.
