If possible, include Team Viewer as a part of the COMMANDseries install and have it as an option to open from a shortcut in the Help menu. This would be helpful when having to diagnose an issue for a customer as it would allow them to launch Team Viewer without having to download anything. This would make the process easier when needing to look at a customer's system.
Would be nice if there was no "3rd party" involved or if a 3rd party is needed, a "command" branded application version of it. Team Viewer, for example, does have the "branded" ability and for the end users, would assure they "clicked" the right button.
