Option for Smart guides to ignore objects outside isolation
Sometimes you want to isolate certain objects to not mess with everything else. Unfortunatelly, you can't isolate parts of different groups (but that is the other topic—'making isolation more like 'solo' in AE). But even when you have isolated something, Smart Guides still want to snap to objects other then you want to work with. Sometimes it's fine, yeah, but mostly I want SG to ignore everything else but isolated stuff. Please make a tick somewhere for this.

The latest Beta now has a dedicated option for this in Preferences > Smart Guides section, in Limit Snapping area. We can now choose if we want to Snap to Isolated Objects ('...only, when isolated' — the name is not clear at the moment).
This is a WIP feature, and the team desperately needs your feedback on it. Please test it and comment if it works as expected (or not).

Works best with these two requests:
Disable smart guides to some specific object/layer

And add ad setting to ignore locked layers as well!

Smart guides should definitely have more preferences associated with it in general.
Its quite basic at the moment -

Hey Egor - I like the sound of this and just came to suggest a slightly different option whereby smart guides are set to ignore everything on a specific layer selected via the layers options. Especially useful for times when you put reference material on a locked layer beneath which is there for visual reference only.
I'd say the option for exclusion of anything outside of isolation belongs in preferences > smart guides
