Reset button on cover if it has been edited

[Palloxin]

Describe your suggested feature

A reset button in the cover section (when opened) IF it has been manually modified

In this position↑

The reset should also "re-link" the cover to the source dependency. If the source updates the entry and the user updates, the cover should follow.

Other details

Currently it's cumbersome to do so.
