As it stands, the tacmap is really minimalistic and barely shows anything. To actually gauge how a ship is doing in combat, you have to physically switch camera to it, which is annoying when you just want to have a glance at your fleet for a few moments before getting back into the action.
A really big part of this problem is the lack of a flux gauge. The only things you can really easily tell is the current hull level and armor grid of ships you hover over, and their orientation, as well as incoming missiles, when a big part of knowing when a ship is in trouble is with flux. I often see one of my small frigates fighting a group of ships from a distance, and I assume "oh it's probably okay, it has 100% hull", but when I focus in on it, it's flamed out, it's nearly fluxed out, it's shield is facing the wrong way, and half it's weapons are disabled. At the very least, having a flux gauge (and maybe a shield arc visualization) would be really helpful for actually determining how much trouble a ship might be in at a glance.
