Proposal for Opera changes and new features for mail.opera.com

I'd like to share my hopes and wishes about Opera's evolution.

1) Many of us uses Opera mail client M2 as default mail client, but i think it would be better if Opera substitute M2 client with their excellent mail.opera.com web service for two valuable reasons at last. The first one is that we can use it totally as a mail client substitute (except for the lack of rss newsfeed). The second one is that we can access to every Opera installation to the same client, without downloading duplicates of the same email of different devices.

2) Look and feel changes: Opera Featherweight is a very next step into creating a polite and streamlined user interface, but it has still some problems on Aero themed Windows and Linux Platform.
On Windows: the Opera window is missing a vertical border which gives the user the impression to do not have a polished and refined Browser, it looks unfinished, and there is not a clear separation from the page you are browsing and the border of the browser, the result is ugly. This is a design related problem that should fixed as soon as possible since the average user do care a lot of the user interface, since he is not capable of judge many other aspects which makes Opera a special browser. To be clear of what i'm talking about I've posted a screenshot:

On Linux: Opera looks not native and uncomfortable, it would be nice to have a complete and well integrated GTK3 interface, not a simple adaptation which looks acceptable to all desktops environments.

3) Bittorrent: Bittorrent Protocol is not well implemented in the browser and the lack of features makes this feature almost useless. I propose to use libtorrent in association of a web interface which can be used inside the browser to manage our downloads.

4) mail.opera.com newsfeed feature and calendar: It would be useful to synch our rss and calendar into the web service.

Edit: added Bittorrent renewal propose.
