[mew-int 2724] switching between different accounts + synchronization of marks with gmail

Hi,

I've just started using mew, and have two questions.
1) I mainly use two different e-mail accounts, one "private" and one for
university. I have set-up mew for both, using mew-config-alist like
so: 

(setq mew-config-alist
      '(("uni" ( ...))
        ("private" (...))))

This works fine, but i haven't found a convenient way to switch
between reading both accounts yet. Currently, I switch case using 
M-X mew-case-set, and then start mew again manually using M-X
mew. Should I just write some lisp macros to automate this, or 
how do other users go about this? It feels like there 
should be some function inside of Mew to help with this?

2) How can make Mew set
messages as "(un)read" or "(un)flagged" on the server? Making
appropriate marks in the summary buffer and pressing "x" has no
effect. What is the correct way?

Thank you,

Thomas
