hold frame

So... I set up timeline and scrub through to a point I like - think I'll edit an asset on screen and click on it - the whole timeline resets back to frame 0. Most annoying.
1. Can this be changed to the frame time stays in place whilst editing assets (even more wanted as ProBuilder has now bene added and encourages in scene editing)?
2. While I'm asking - how about a simple way to 'isolate' an object as well - i.e. automatically hides everything else when an object is 'isolated'.

 

Did you block the timeline? I dont have this problem , maybe I didn't understand well
