Would it be possible to not require a button to trigger the coin selection? Or would that be too involved?
I was thinking of displaying the selecting coins once they've set the feerate and (at least) one address. If they tick any coin before or after filling up the feerate/addresses, we don't do any automated selection.

The new "Auto-select" button uses automated coin selection to select coins for a spend, which the user can then modify as required.
The button can only be clicked once the recipients and feerate have been validated, and it does not appear when creating a self-send.
I haven't added any validation on the amount before making the button clickable, but it may be hard to anticipate all coin selection errors once fees are taken into consideration.

I think that should be fine. I've made an initial attempt at that now, which seems to work as you describe. It may need some refactoring and better handling of errors from coin selection. |

This is ready for initial testing. When creating a new spend, coins are selected automatically unless the user edits the selection, after which point only manual selection will be used. In case auto-selection fails due to insufficient funds, the amount left to select will show a positive value. If the user then edits the recipient amounts and/or feerate, coin selection will run again. A spend created using auto-selection should pay the same fee and give the same change amount as another spend created using manual selection with the same auto-selected coins. |

Got a crash on my first try :p. It might be because i used a receive address as destination address? logsEDIT: this was reported upstream (bitcoindevkit/bdk#1072 (comment)). |

Due to how the feerate will be converted from Perhaps we should modify the GUI to use |

The latter seems preferable, the GUI shouldn't crash just because an error is returned by a command. EDIT: arf, i read too quickly. It implies we tackle #800 first.. |

I think the `[WIP]` label and draft status can be removed?

One issue with creating a spend on every update is how the change address derivation index will keep being increased over and over. I think that's fine for now.

After #821, we could call create_spend here with a fixed change address just for coin selection purposes, and then increment the change index only when the user clicks "Next" and the PSBT is generated on screen.

This adds automated coin selection from #560 to the GUI.
The new "Auto-select" button uses automated coin selection to select coins for a spend, which the user can then modify as required.
The button can only be clicked once the recipients and feerate have been validated, and it does not appear when creating a self-send.
I haven't added any validation on the amount before making the button clickable, but it may be hard to anticipate all coin selection errors once fees are taken into consideration.
