Gentlemen,
Glad to hear you all miss the TAB key. I can tell you that I was testing the fix today and I am hopeful we will get through our QA process and get the updated version out to you in the coming weeks.
In addition to fixing the TAB key, in the VNC Viewer, we are also upgrading the viewer to enable some new features. I am confident you will find it useful.
Your patience is appreciated and keep this feedback coming.
Chad
