We need a way to create a Hotkey for Isolate/UnIsolate.
I use Isolate all the time to design in specific components, but the Menu method for Isolate/UnIsolate takes a lot of time and patience to get the right component from the tree.
Imagine if we could hit "Shift-I" or a single keystroke, select a component and it would Isolate that components. When the keystroke is selected again "Shift-I" it would UnIsolate the current isolated component, and possibly allow you to select another component to Isolate or hit Esc, to get out of the command.
