I got it installed and all seems well ( 2 attempts :>) This weekend will be when I really dive into it.
Another thing that is maybe not that intuitive: Don't by shy dragging things onto hotbars. Besides spells, try dragging some petals, potions, ethys, runebooks, etc. to the hotbars. Right click and you can assign hotkeys, like "space" for your ehty, "p" for some petals.
One thing I do on every char: I have a runebook where the default location goes to my house. You can place a recall spell in a hotbar slot, right click it, select "target stored" and then target the runebook. When you now right click again and assign a hotkey, it will instantly recall you home with only one key
You can also store targets like your friends, or pets. Like you have 5 healing spells in hotbar slots and setup this "target stored" for your party members. Also works for shovels and T-Maps. Those hotbars are deffo worth are a look.
