On my engineer I used an add on that I could stack multiple transporting devices into one button, ie: hearthstones, whistle, toys for transporting around the game.
You would basically make a macro that was something like ##heartstone, ##flight whistle, ## garrison… etc etc etc…you would then drag it to a spot on your tool bar and when you right clicked it all the hearths you had, toys for transporting around would come up in a rectangle or square box depending how many items you had in the macro when you right clicked it then left clicked that item to use it.
I used it for transporting but I spose you could use it for anything to group it together into one button on your tool bar.
Some people have mentioned an alternative that was the round circle of abilities I could fill in and a button that flares out when you hover over it but those simply aren’t it and I just feel they don’t work as well.
Anyone know what add on I’m talking about where you added the name of the “something” to a small macro to make up the tool bar spot on your tool bar?
