Not discounting most of the points here, but just wanted to mention a couple of things:
- If you’re on Android, Quick Dynalist is a fantastic app to quickly capture to your inbox. I use it everyday. It would be great if Dynalist had better quick add to inbox natively, but until then it does the job well.
- A few months ago they rolled out a “dragging indent” feature which I think addresses the problem you mentioned. You simply drag the item under another item to the right of the item (kind of hard to describe, see this link with an illustrative screen recording: https://blog.dynalist.io/2019-june-update/).
