Add what was asked in #544

Looks good.

1. Could you add a "to clipboard" in the strings? So "Copy all sectors to clipboard". I feel like this could add some context.
2. Maybe all these somewhat similar functions should be next to each other. Could you move "Share", "Copy all sectors to clipboard" and "Export Dump" at the very end of the menu (in that order)? Thanks.
