True, but in muun's case it seems like the clean & simple UX was their paramount priority. I'm not against that. The problem here is that they tried to "hide complexity" but complexity still exists.

I wrote to them suggesting the addition of an "advanced mode" that would unlock these features (coin selection, index retrieval, etc). It's not hard to do, and it could have been added incrementally. But apparently they were not interested in doing that.
