Very small issue and might be more of a bug on Gnome's part than anything, but the file name for a downloaded config, {ClientID}-{NetworkID}-netmaker-client.conf, will not import successfully in Gnome. Gnome Settings will complain about a missing hostname then crash (lol). Workaround is simple, just rename the file to something without hyphens (-). Again, could be more of a Gnome issue than anything, but something to be aware of for the Linux folk.
