Aqua mail on Chromebook size and attachments

[Helikon]

I have some problems with my AquaMail on my Chromebook. I cant find out how to resize the screen (or make it full screen) and when I try to open an .docx attachment, I get the following error:
"No application(s) found to open the attachment whose type is:...." although I have installed Google Docs. Can anybody tell me how to fix these problems.

Thanks in advance!

Re: resizing: the app is set to "tablet sized screen".

Being able to resize Chrome / ARC apps only appeared recently, I haven't had the time to look at it yet.

Re: attachments: sounds like an integration issue.

As far as Aqua is concerned, it's running on Android, and Chrome intercepts certain functions and "bridges" them into Chrome itself. So that's pretty much out of my hands.
