Missing address across devices + idea for hide/temporary addresses

[peynh1]

Issue
One of my wallet addresses didn’t appear on Chrome (desktop) but did show on mobile (same wallet).
Even when I tried to add new addresses via the “+” button on Chrome, this specific address didn’t show — although it’s clearly part of the wallet.
I fixed the issue by logging out and logging back in via the Login File.

Expected behavior
All wallet addresses should sync and appear consistently across all devices and browsers.

Suggestion
Add an option to hide or mark addresses as temporary, like Kaspa or Chrome’s incognito mode.
Add a “Sync all addresses” button (in settings or similar) with checkboxes:

☑️ Addresses with balance (default)
☐ Addresses used in the past

If funds are sent to a "deactivated" address, show a badge or unread icon to indicate that there are funds on it.

This would solve sync inconsistencies and help privacy-focused users keep their wallet cleaner.
