I would agree it's minor, but when most peoples screens these days are at least 1920x1080, why is there a separate pop out menu for Voicemail, Recordings, and Settings? Can you just put them under Contacts please?
Let's not kid ourselves. 3CX is great but the UI could use a lot of work.
Admin console Dashboard for example: Why can we click on Services or Activity Logs to view those items, but cannot do the same for Recordings, Chat Logs, or Call Logs?
