Just a simple “right click” on the client tray and then selecting an option to go to a custom defined URL. The text of the menu option itself would be definable as well.
EX. SCENARIO: So if I wanted my users to have a quick access link to message me via email. SOLUTION: I could have a right click option called “Contact Aaron” which goes to a URL that has my contact form on it for then to fill out and submit.
