Scheduler: Success Screen

[dergigi]

Nothing happens on success, would be good to show a big fat ✅ or something, at least.

Since this is a long-running process I assume that users will leave it open/running and as it is now, currently, even if it is successful, they will be greeted with the "Scheduler" screen again, and possibly a warning (because of a lack of UTXOs or some such). For example:

In the future, it would be great to add a "fee report" or something similar. A summary, like a reverse-earning report. Just a thought.

Good idea.

One difficulty comes to mind: At the moment we cannot really distinguish between a successful and a failed scheduler run (e.g. because of no retries left), other than by applying heuristics: e.g. either none or only frozen utxos left in the wallet after a scheduler run. Still thinking about how to communicate this to the user.
