Although I love the simple ability to toggle my availability with a flip of a switch in SWSD from my profile dropdown, it would definitely be nice for Techs/Service Agent Users to be able to set up their own hours of availability from their personal settings. For example, if I work 8AM-5PM, the Availability switch should automatically turn on at 8AM and then automatically switch back off at 5PM. In situations where techs are unexpectedly out of the office or techs simply forget to turn it off/on, it can leave tickets unattended and the only solution would be to contact an administrator to impersonate their account to switch their availability (which isn't always efficient if the Administrator isn't available).
