v2.4.42 is now in the library, this should fix the flickering and includes the hide .vcv option for Purfenator, but it does not include ZAM yet, it still needs some thought/work.
You may have noticed that recent modules use this community forum instead of my GitHub manual site, so FYI future modules will not be added to the manual, it can be considered deprecated, but I will leave it in place for now.
If/when I update older modules, I will create new threads for them here and move over the documentation, it is always a hassle to update and reduces my productivity, eventually it will go away…
