Pipelines - Broken or how do they work?

[HorstBaerbel]

Say I want to render some color bars and use them as an input for color-mapping multiple groups / modules. I thought this was what pipelines were for. I'd expect the output to be never visible, but still rendered / generated in the background if I enable the pipeline / group. But whether I check the pipeline box or not makes absolutely no difference... What am I doing wrong?
[EDIT]: I've found the Alt-Click "Skip drawing to output canvas" feature which seems to do the right thing. Shouldn't that rather be a proper checkbox in the group settings?! And them wth are pipelines for?!

@HorstBaerbel Here's what pipeline does: https://modv.vcync.gl/v3/documentation/groups.html#pipeline

"Skip drawing to output canvas" does what you want it to do, based on your use-case.
It could be its own checkbox, but there's not much room left in the UI, group settings would start to become quite long.

I did see #854 which might be some sort of solution to this, however I'd prefer to redesign the group controls rather than just making them taller.

I've read the docs, but still do not understand what pipeline can be used for. Isn't a group with a single module and "Skip drawing to output canvas" basically the same thing?
