Thanks.

Would it be a better UI if instead of prompting with

  Enable custom theme:
  Disable custom theme:

we would prompt like this:

  Switch off theme (default none):
  Switch on theme:

I think this order is preferable, since "switch-SOMETHING"
conceptually means turn off OLD, then turn on NEW, not the other way
around, even if the implementation does it in the reverse order for
some technical reasons.
