Thank you, but I meant to relay something else mainly. I like having a centralized place but I do like those 2 ways of skin a cat - how you reffered to it. I liked that redundancy (but still kept in order in a way) in that case.
I can't give the error since all is fine now after I installed python-psutil and then saved the menu.
Before I installed python-psutil I couldn't open panel profiles at all.
Command line error from before I installed python-psutil was something like - "missing module psutil". (I then installed psutils, saw no change, then installed pyhton-psutil, which THEN allowed me to open pannel profile from any place.)
I had some other obscure error after saving by the commandline without a suffix and trying to load it - "no such file or directory" or something like that. This is my error probably (missed postfix? other wrong use of command/procedure?). And I couldn't load that old original save by doing simple tasks on the UI as well.
Save and load of the actual saved profile (I had some other error meanwhile/in between which I don't well remember enough to minimally described, of "wrong" configuration loaded at 1st,) only worked correctly for me after I initially had chosen a pre-built profile, modified and saved it, which by the UI ofc also added the archive postfix automatically. (in this case I savd and loaded by the UI, but I believe it now works everywhere.)
Now all is fine. But as said, I had to install python-psutil for it to work (or even start) for me.
I hope it's clear now and thank you for your reading and response.
