Output is always to the session directory or in subdirectories of it.
No way to put it into a parallel hierarchy.
No way to construct output paths according to variables (they can do it with names, why not directories?).
The need to have a session is just a major PITA.

Well, Andreas, no doubt you know your systems. I mean, i've seen the Bibble Bible you wrote. But, this is plain wrong. You can have the recipes output any which way you like.
However, it is true that it cannot be done with variables.
Just to avoid any fanboy remarks, i'm not one. C1's DAM capabilities, or rather lack thereof, steered me away initially. Later, i found out that the session route combined with a real dam (or at least a more proper one), let me do all the stuff that is being called for here and in other forums.
But, not unlike Bibble in its glory days, this is a complex piece of software and one really needs to hang in there to get it to work for ones own workflow. I know it took me about a year and a half after Phase One kinda abandoned Media Pro to find a way of working that suits me. YMMV. I do feel though that making blanket statements about some software on how it does or doesn't work without getting to the bottom of it (or so it seems) isn't particularly helpful.
Other than that, i believe you are quite well versed in iMatch and i think that is every bit as good as the DAM i use, but just not Mac.
If anyone has any questions about C1 and wants to call my "bluff", of course i will see if i can help. The same goes for all other applications i use, photo supreme, photo ninja, affinity photo, pixelmator, zerene stacker, photomatix pro, autopano giga, lightzone, to name a few.
