Some thoughts about the scanning info screen topic:

• Instead of having the scan info as a completely separate screen, I think using a Drawer (on the right side) would be nice. We can expand this drawer either by interacting with the scan bar, clicking the '>' arrow, or by clicking on the 'bitcoin' icon in the top right
• Even when we're not scanning, we should still allow users to open this drawer by clicking the bitcoin icon and it will display a simple 'You're up to date' message, along with (maybe, if we want to) the block height or something
• We can treat this screen as a general 'chain overview' screen. We could show blindbit connection status there, but we could also display some other cool stuff like the current fee rates
