This kinda sounds related:
“separate model layer visibility from the layouts” … hmmm
I use the whole ‘hide in detail’ thing alot to mitigate the issue, but yes if there were ‘separate model layer visibility relative to layouts’ then that might be a game changer.
Because the whole hide detail / show detail thing becomes high maintenance. If layouts could be linked to layers, then different layouts relative to different layers would be much more efficient to maintain. Unless I’m still missing something 
I’ll try to study that class video and any others that might help.
