The problem that this feature will solve:
Not being able to toggle isolate on / off while using build tools
Brief description of the outcomes that you expect from this feature:
having a shortcut to toggle isolation would be helpful regardless of context (if a tool is being used or not). for instance if you were replacing a face and need to pick an object that’s behind another object. you can’t isolate, pick the source face, un-isolate,then pick the target face. (at least the right click option disappeared once I was mid-selection with the tool)
What can’t you achieve without this feature?
Keeps the work flowing. it’s clunky without, need to resort to tumbling and zooming and awkward picking faces.
