I’d like to know why, if one you have a commented out activity you can drag and and drop other activities inside the “commented out” flow, it’s not possible to disable several actitivites at once that had been previously selected (with CTRL+click on the activity; SHIFT+click, unfortunately, doesn’t work for selecting a range of activities - which, in my opinion, should also be regaded as a bug).
I wished that, once you have several activities selected, the “Disable Activity” right click button option would disable all them, if possible putting the consecutive ones in the same commented-out flow (avoiding surrounding each activity with its own single “Comment out” box, if possible).
