Make web mail choice immediate default with no delay

At present, when you log on to webmail you get a choice of Roundcube, Horde and Squirrelmail. You have then a choice of making one your default, and if you select that it will then automatically open after a delay of 5 seconds every time you go to webmail. Can I suggest that in their next revision they give you the additional choice of making one your immediate default, with no delay? That would take us back to where we were before the security upgrade, while still having the security of the session tokens?
