I would like to suggest the following change in handling .key files. IMHO you would use a key file to keep it seperate from a keepass DB file which you synchronise using cloud services or something similar. So I would like to see [the option] that the presence of the key file is being ignored after an initial sync so that it can be removed from cloud storage for additional security, so that sync of DB file only could be done successfully in these cases as well. Would be also nice to toggle an "offline" mode which doesn't try to carry out any sync, offering the user to initiate a sync manually. Being able to get the key file from seperate sources (iPhone file storage / sharing (e.g. Nextcloud app)) would be an additional bonus
TBH - being forced to have both the DB file and the key file online at the same storage runs contrary to the idea of adding additional security by a key file.
@Dev: Thanks for the good work - take care
