Client rewrite for RoundCube

I understand your concepts for enhancing the client code of RoundCube
and I mostly agree with your ideas. The current code is very straight
forward and grew with the application. It currently counts about 3900
lines! All actions are held in one object and are (mostly) invoked
using one method: rcube.command();
I already wanted to split the code into task-specific files such as
mail, address book and settings where all methods are added to the
main class using rcube_webmail.prototype.nnn. Also creating some new
classes for list functionality etc. was in my mind.
There also popped up some plans and suggestions to make the client
even more ajaxy and eliminate full page loads when switching between
list, view and compose mode. Probably that's something we could
include in this concept.
Actually I agree with a rewrite as you suggested, the only
disadvantage I see, is that this will take some time and it will stop
the current development because merging could become very difficult.
That's also the reason, why I cc-ed the mailing list because that's a
task that concerns all developers. For me, it's no problem because
I'll go on holiday for more than a month soon and will not work on the
