I haven't seen anybody disagreeing with Belen's proposal, yet. So it
seems we are approaching a UI consensus?

Still rather tricky and difficult to test. Maybe also not worth the
effort as this is a rather special corner case. Just stick with multiple
currencies if you used them in the past, at least for now?

In Android there's this Action Mode pattern where you long tap a list
item and then can select more or all and perform actions on the selected
items.

I have recently implemented something similar for Briar's private
message deletion:

Agreed.

We could integrate those events into the exchange management UI somehow,
or in some developer section or hide them completely. All fine with me.

Great, I am all for hiding events that have no relevance for the user.
Ideally, already in wallet-core, so they don't even arrive in the UI layer.

I don't know the gmail app, but what Florian suggests sounds like the
Action Mode selection on a filtered list.

Once event deletion is available in the wallet-core API, I'd be happy to
implement that in the wallet app.
