Since I don't know much about how the interpreter part works, Its still
quite confusing.
And I think that having both checkbox and a dropdown might not be helping.
First of all, is there a possibility that by setting 'Per User' or 'Per
Note', some of the previous settings (isolated or scoped) become meaningless?
Otherwise, I think this could be a good improvement:

First drop down (globally, per user, per note)
Second drop down (shared, scoped, isolated)
Would the 'Connect to existing process' option be part of that second
dropdown? or is it not related?
