Quick(er) add for mobile: Swipe line in outline to quick-add new item under it
Adding a new item under an existing project or list in their outline, is probably the single task anyone wants to do most quickly on a mobile device!
With this in mind, I wish one of the convenient swipe gestures on mobile was reserved for quickly adding a new item under any given line in the outline.
I'm aware that this would replace or extend current swiping options on mobile. However, I think the ability to quickly add a new task under a specific list/project in the outline, via a precise gesture, might be more important than even the current swipe options.
Again, I'm aware that this would replace or extend current swiping options on mobile. So below follows my (personal) feedback on those current swiping options, and their value relative to the proposed swipe-to-add-an-item option.
Current swiping set-up is just okay. I like swipe right to zoom, and use it a lot. It's definitely not the same as swipe-to-quickly-add, though. There's still lots of screen clicks and repositioning to start typing a new task, even after one has zoomed to the desired place in the outline.
Next: swipe left for mark-complete and hard-left for delete has NEVER been my favorite. For one, I'm afraid I'm accidentally going to delete something so I almost never use it. Secondly, I find it's oddly redundant with the quick-to-tick checkboxes for "completable" tasks! Actually, I find the prominence of a default, end-of-line "mark-completed" option off-putting on desktop, too. Personally I don't see everything in my outline -- especially headers -- as "completable." So I like the control of using checkboxes to custom-specify (and draw attention to!) items in my outline that ARE completable. I guess it follows that I'm not that into the swipe-absolutely-any-line-item-to-mark-it-complete feature on mobile either.
