Yes, this is something that we will improve in Krita 2.0. We had a long 
discussion about where adjustment layers belonged -- as filters embedded in 
the layer stack, or as masks + filter per layer. I was thinking the latter 
would be more useful, but others wanted the former. In 2.0, we'll have both.

Additionally, we're working on making all filters and all composition work on 
a selectable subset of channels -- so you can set a filter to work on a and 
b, and composition on L and a, for instance.

Tonemapping is on the todo for 2.0 as well: Cyrille Berger is the man who has 
it on his programme. I'm not sure whether he already knew about the links you 
give here, but I certainly didn't. Thanks!

Thanks again for the link. Having built-in panorama functionality is not on 
the todo, although it would be a good plugin project for an interested 
hacker. I've had one report of a user who liked editing the finished 
panoramas in Krita because only Krita could load his very wide images :-).

Interesting links -- but I'm not sure whether we'll have time to implement 
stuff like this for 2.0. Our todo is already somewhat large:

There is the beginning of a siox plugin for Krita, but unfortunately Michael 
Thaler, who was working on it, got really busy with his new job after 
completing his Phd.

Ha, yes -- I know about MoXi. For 2.0 at least, I've got the beginnings of a 
semi-decent Chinese brush simulation already.

Thanks for your mail & for the links! We're working on performance, too :-).
