V1.30 - Feature - now supporting holding down SHIFT on the combat groups visibility button which will force all but the active combat group to go invisible and holding down CTRL on combat groups visibility button which will force all but the active combat group to go visible. Active group will toggle as normal regardless.
Was in my weekly game when I had to setup a bunch of groups then make them all carriers then get all the groups back displayed on my CT. It was a royal pain. To assist me next time I have a ton of CT entries and want to turn off or on all the groups at once I added this new feature. It does not change the toggle of the actual Visible button press for the active group when holding down SHIFT(turn all other groups off) or CTRL(turn all other groups on). This makes life lazier for me.
