We are working towards letting the user save a file containing the descriptor encrypted with all the xpubs included in it (see the following delving post for more details).

We should adjust the Liana UI in the following ways (see mockups here in the "Backup / Export & Import" part):

• In the installer: at the "Back up your wallet" step, the user should have the possibility to download the encrypted descriptor backup and to copy the plain-text descriptor. Some wording needs to be adjusted (first proposals in the mockup).
• In the Settings>Wallet section: to avoid confusion I propose to remove the "Backup" and "Restore" option, which were related to the state of the wallet (labels, aliases and so on) and add a "Back Up Descriptor" option together with the plain text copy.
• In the Settings>Import/Export section: I would change some wording to convey the difference between the wallet state export and the backup previously described (proposals in the mockup).

The Restore process will be the most impacted in this flow, but it will be dealt with in a separate issue.
