already did. 
imap idle support with libetpan is relatively easy
Just need a thread with the following: (just an ugly and quickly
written code)

while(1) {
  if (r = mailimap_idle(imap) ) {
      /*something goes wrong: give up?*/
    }             
                  
    int fd;       
    int maxfd;    
    fd_set readfds;
    struct timeval delay;
                  
    fd = mailimap_idle_get_fd(imap);
    FD_ZERO(&readfds);
    FD_SET(fd, &readfds);
    maxfd = fd;   
                  
    delay.tv_sec = 30 * 60; /*ugly, but going from rfc ... */
    delay.tv_usec = 0;
                  
    r = select(maxfd + 1, &readfds, NULL, NULL, &delay);
    if (r == 0) {
      /* timeout */
    }
    else if (r == -1) {
      /*something goes wrong again ... */
    }
    else {
      if (FD_ISSET(fd , &readfds)) {
        /* has something on socket */
        if (r = mailimap_idle_done(imap) ) {
          /*yet another error*/
        }
	/* here we go - process mail required here ...*/
        
      }
    }

}
/*other code ... blablabla*/

the question(s) is:
1. are there any description of claws mail client architecture (to
avoid a lot of code view)?
2. could someone point me to related sources in claws code base ?
(otherwise it will take a more time to do so myself)
3. not familiar with GUI (settings should be done within gui code) and
it will be nice if someone will help me with that, is it possible at
the moment ? 
4. are there any problems in claws with multithreading ?

thanks,
