Well, Opensched does it, AFAIK.  And doesn't MS-Project solve this too?
(I never used *any* MS-software, not even Windows ;-), so I don't know.)

Maybe intergrate the Opensched algorithm?

Maybe with priorities on tasks?  If most (all?) tasks have a
different priority, this should limit the possibilities (together
with all kinds of other contraints, like dependencies, fixed
allocation/starting time/dealines, etc.).

Exactly what I see in real life, so it should indeed be possible to pin
long-lasting tasks for someone for, say, 25% of his/her time.

I'm curious how this will work, will certainly take a look at it.
I'm not a planning expert, just want to use the tool, and considered
it pretty useless for my purpose with the lack of this functionality.
