Does this mean that if developers started to pump out decorators to theme 
Haiku, people would not be able to use them together with SAT?

Don't get me wrong. I think it's fantastic that the SAT code is now separated 
from the app_server. This makes things much cleaner and safer. I'm just 
wondering if this will hinder the use of decorators for actually changing the 
decors.

I think you are right in that the application will be better at understanding 
what a window represents. That said, I'm not even sure I want persistency at 
all. What I'm more interested in is setting up rules for where different types 
of windows should go.

I want all terminal windows in one group, not a terminal opened in a specific 
directory to go where it happened to be last time. This could be possible on a 
general basis, but if you want to make the rules more complicated, they will be 
application specific.

In Web+ you might want to stack windows where the URL has the same hostname or 
resolve to the same IP address, or maybe where similar protocols are used. 
There is no way the app_server can guess this.

I also think different users will have different criteria on how to recognise 
window patterns, which is also a reason why simply saving the current layout is 
not sufficient. When saving the group id of a browser window, is it associated 
with the exact URL, the hostname, or something else?
