I would like to second some of these...
#2... I need to find a machine based on who is logging into it or its IP address (these are SUPER COMMON) ways that I search for machines in other RMMs.
#5... If I remote into a machine then need to RDP from that machine to another, I can't control keyboard inputs in that second session. This is more common than you think.

I'll add... File transfer and being able to Copy/Paste from my host machine are basic items that aren't available to me now. Super annoying to have to paste text into a chat window then re-copy it from the remote machine.
