First suggestion is about how specific Ifs don't have a "When Rotuine Ends" feature. I have created a Routines that sets the volume to max if specific people call me, as I prefer to keep my phone muted or on vibrate unless it's important. The routine works great, aside from the fact that once the call has ended, the volume doesn't go back to its previous state, nor is there the opinion to "When Routine Ends". It would be great to have this option like with other Ifs.
Second Suggestion is to add more than just "Reverse these actions" to the "When Routine Ends" option. Give the user the option to do other things after the routine has ended, instead of just reversing.
