I confess I don't use coin_control very often, I rarely use it in Bitcoin Core, which already offers a satisfactory coin selection, in my opinion.
Moreover, Bitcoin Core's enabled Coin Control interface is extremely crude and ugly. Once enabled, there should only be a single button on the send tab for any user to use, similar to how some wallets implement this.
The enabled coin_control interface takes up a lot of unnecessary space on the send tab, everything could be replaced with a single button or something similar that doesn't clutter the UI unnecessarily.
