Proposals for Aqua mail-client android application

I use to have "Touchdown for smartphones" application to read mails for MSExchange mail server - perfect application and very customizable ! I loved it! But I moved to IMAP account and Touchdown does not support IMAP, so I have to switch from it to other application.

I did investigation of mail clients for Android and following application is really great and convenient for my workflow and usage.
Aqua mail client.

List of my proposals to make me forget about Touchdown:
1) New option: Do not mark Read on server.
2) How it is possible to filter UnRead mails in Folder
3) hide amount of mails in folder
4) new potion: hide Folder from list of synced Folders

Mount Nexus5 to Ubuntu 12.04

Instruction how to connect Nexus phone to Ubuntu 12.04:

1) Activate developer options on Nexus 5, instructions, that mode have to be switched ON always to be mounted.

2) just follow http://bernaerts.dyndns.org/linux/74-ubuntu/268-ubuntu-automount-any-mtp-device , at the end of article there is a script that do all that steps automatically (that require only 2 chapter to be done).

ATTENTION: unlock phone before connection to PC, if phone is locked auto connection/mount is not happen!!!!

it works for any device - Nexus 4, Nexus 5, Nexus 7, .... that use MTP protocol.

Only one minor nuance is noticed: Nautilus does not copy files/folders if you use Tabs in Nautilus, workaround just use separate nautilus windows.
