Actually, Yanfly never made it for ACE. The ACE script you are thinking of lets you only select from random skills to be chained, not selected via player input. And don't EVER talk about a scripter like that. Remember they make most of their scripts/plug-ins for free. In fact, most of them have stopped doing that just because of attitudes like that and THAT is why they now only work for $$$ or patreon donations. If people keep that up, next RPGMaker the only plug-ins or scripts or whatever it is called that will be available for free will be...nada. Nilch. None. Is that what you want? If so just keep it up.
