PLEASE bring BACK Keyframable VISIBILITY (not only Keyframable Render Visibility)

in 2.79 if you wanted to render things to appear and then disappear you'd just keyframe render visibility and while you keyframe that ,you'd keyframe normal visibility to be able to have a preview in the viewport

i did a full project that required a ton of HIDE AND SHOW visibility ,and it was TORTURE to do: because i didn't have a preview before rendering (Constantly Crashing , i speculate its Ram or rendering as PNG /FFMPEG insthead of MP4)

This doesn't need a mockup ,it was already in earlier 2.8 versions ,maybe just right click and keyframe Visibility and Render ,maybe they could have a little dot between them so you can keyframe the dot and that indicates its gonna show in preview too

the way 2.79 did it ,was fine so even if there is no addition but just bringing back its old way its way more useable than now where i have to manually hide stuff while previewing
