[Evolution] New user, few questions

[sweetthdevil gmail com]

Hi all,

I would like to first of all thank you all for sharing what seems to me
within few minutes a great tool!

I always use Thunderbird in the past, and wish to move to evolution in
order to enjoy the integration with gnome shell. 

Anyway now to the questions:

 I am using two google account (mail/calendar/etc)

- I wanted to rename the calendar name (listed as "Calendar" within
evolution) renaming it from evolution doesn't work, and I can't find an
option within gmail. 

- I want to be able to re-arrange the folder, for that I was using a plugin call conversation in Thunderbird 
(see below for url). This basically will show you only what's important for you.
I.E. in my case, my two inbox folder (and the possibility to have one view with the two inbox together, and 
the RSS feed. The rest can be expand only when needed. 
The view is therefore tidier not to mention the fact you do not have the need to scroll up and down all the 
time to access different mailboxes.

- As I am only using my two gmail account I do not need the "On this Computer" folder can we remove them? 
Only if the RSS folder can then be move elsewhere. 

- Again as I am using two gmail account I do not want to keep my entire inbox locally in order to save 
hard-drive space, so an option to keep only the last 30 days of email locally would be great.

many thanks for reading,

Looking forward for your reply,
