Yeah it's only for a compatibility check and so that nano stakes users can use it for free.
The main thing you'll want to look at is the preset bets, button cutoff raises and the action hotkeys (#3) all on the betting TAB. From that you'll get a quick idea how much it helps. Plus you can take a look around the GUI and see what else it's got (planner, stacker etc).
To try it, make sure your chat is on
dealer actions. There is a quick setup guide
here.
