Problem:
The icon for ACTool is not on the Decal bar, even though the Companion plugin is loaded in Decal

Solution:
ACTool doesn't use a Decal UI and is not supposed display an icon in the Decal bar.
You interact with ACTool from within AC by using the F2 hotkey to start and stop the macro. There are also commands that can be typed into the chat window, as follows:


/actstart mymacro.mac - starts macro running!
/actstop - stops macro
/actpause - pauses or resume macro
/actinv - dumps contents of inventory to inventory.csv in AC directory
/actcmd n - runs an AC Tool event - see Procedure help for more information
/actguid - displays the current selected items GUID and copies it to the clipboard
/actequip - list equipped items
