Describe your suggested feature

This feature allows a remote source entry to be detached by moving it to the local source, enabling the following:

• After an extension is discontinued, previously downloaded entries associated with it can be moved to the local source and detached from the remote source.

This action is currently possible but must be performed manually via the file manager. Adding a button to the EntryToolbar would automate this process.

This allows the user to remove the discontinued extension without needing to migrate.
