Playing with Click Bars
More info below the image
This screenshot has 2 Click Bars in it. One is at top middle, and one is at the bottom overlaying my main Action Bar.
The top one demonstrates how images can be used to provide a permanent, interactive indicator for toggling Repeater and Mapped Keys. The button on the left shows Key Maps ON, the button on the right shows Repeater OFF. The Repeater icon shows that, when on, pressing A will broadcast A to others. The Key Map icon shows that, when on, pressing A might send A to one, and Z to another (just indicating that your key may be transformed). Pressing either of the two buttons will toggle Repeater or Mapped Keys, and toggle the icon as well to indicate the state.
The Action Bar overlay is just a simple 12-button bar with transparent buttons that each have text saying +FTL (it would look much prettier if I made an image for each of those buttons to overlay on the Action Bar buttons, but I am trying to demonstrate multiple ways of doing things). The buttons are mapped to the "FTL DPS Keys" map, "DPS 1" through "DPS =" .. meaning that clicking any one of the buttons will do the same thing as pressing the designated Hotkey. Without such a Click Bar, clicking on the first Action Bar button would not necessarily have the same behavior as pressing the 1 key. This bar would be used by people who like to click their Action Bars more than they like to hit Hotkeys.
Come to the chat room for more info, you CAN try out Click Bars if you want!
