Former main healer for a WoW raiding guild here. In that game, most high-end healers utilize mouseover healing.
What that means, is when you cast a beneficial spell (e.g. Science Team), and your mouse pointer is hovering over a friendly unit, the heal should go to that unit. In this way, you can continue to have an enemy target selected while you're healing someone. You don't have to actually select the unit you want to heal, you simply hover over their health bar and cast the spell. Very handy for reducing unnecessary fatigue, frustration, and wrist strain.
I was just wondering if there is any way to do this in STO. Perhaps a macro, or 3rd party UI add-on. I don't know much about the add-on scene for STO.
I mainly play escorts but I'm leveling up a cruiser and science vessel as well. When they reach high level, I want them to be effective healers and I don't want to be fighting the UI.
