It's extremely difficult to manually work with colors with respect to the complete artwork in isolation mode with the background dimming effect. This should be able to be disabled, while still maintaining group isolation workflow benefits.

In my work flow, I find I would like to isolate more than one object for something, and not necessarily a whole layer. Currently I have to group two or three objects first to do this. I'd like to see being able to isolate selected objects without having to group them first.

Ai does not allow to isolate a text object.
We can workaround it by grouping it first, isolating, selecting all and ungrouping — but why execute these many useless operation instead of one?
Please make it possible.

Literally, you can't isolate a guide, neither with a double clicking or a hotkey. Nothing happens. Please fix this

Ai allows you to isolate a single path within document structure, but it only applies to groups. If you want to isolate a part of the compound path/shape — you won't be able to do it.
I fully understand that this requires Ai to decide what to do with art that is created at this isolation level, especially not ordinary paths: type, mesh, brushes... But this can be checked, both creation and pasting and dragging.
Speaking of compound shapes it would also mean that the boolean result will change.
Still, a very welcome feature.

We need a Real Isolate Like in 3D Apps.(3DS Max - C4d )
I mean that when I select an object /s (better with a toggle shortcut key) I can only see it/them. and when I exit Isolation it turns to the main Scene
no need to create unneeded layers for a simple function
Please make this happen.
Thanks
