I tried @morgencalendar's new assist option. It is infinitely configurable (w/ some defaults), which is great! W/ new pricing +education discount, it's more expensive than @reclaimai, the question for me is, how much customization do I really want (I only need todoist+tasks)
Like, yes I can use morgen to do something like -- oh, propagate stuff based on regex (because I often add stuff like Migraine attack from 4pm-4am) and delete it from original calendar using JS, but maybe I can just do it using google apps script instead, ya know
