My girlfriend had an operation and I was with her in the hospital for a
couple of days. There are other things in the world than GMPI lists, you
know ;-)
I didn't mean to just "post and run", sorry for that.

Sure, that should be fine (I mysteriously missed that part in the req.

Nah, you're right: the plugin developer can handle it best. There must be a

If banks are merely presets collected in some known (not plugin-dependent)
"container-structure", it should be fine with the part in the reqs. I had
missed, yes.
