Just an update that I have a fix for the username display issue all set to go. It should be included in PieFed 1.7.
As for the url, would it be better if the "normal" link option just doesn't pre-populate part of the url. So, it would just insert []() instead of the current [](https://). I think most people are probably pasting urls in, so the pre-populated https:// is probably unnecessary most of the time.
