We've got an odd thing going on here, where tlclient saves a configuration file called tlclient.conf, but is associated to open configuration files with a .tlclient extension. It would be nice if we could figure out something that means that tlclient configuration files created by the client can be copied and reused without having to change their extension.
Rephrasing the summary. We've registered the application/vnd.cendio.thinlinc.clientconf MIME type. https://www.iana.org/assignments/media-types/application/vnd.cendio.thinlinc.clientconf
There is no consensus if it should be possible to open this file or if tlclient.conf and the .tlclient files should be separate concepts. We need to decide what we want and then make sure this is clear for the users.
