Kaseya's live connect is freaking sweet. When you "live connect" to a customer, it brings up a dashboard that shows in real-time cpu, memory usage, a mini screen of their actual screen (without you being able to interact), also the cursor doesn't blink from this. It also shows other most important information right at a glance, as well as gives you 5 script actions you can take.
I wish MSP Anywhere had this option to turn on/off if we wanted it.
it also has all sorts of options on the left, regedit, command (ps and cmd), chat, event logs, file browser, service control, process control, even direct access to ticketing.
