Yikes, added stuff, hard stuff, to do. Sort of poked about for an online todo list maker. Have wordflowy, but it limits me to only so many times per month, and i'm going to be doing/checking off/adding a lot.
Tried rapidtables list maker, checkli, and checkvist. Finally returned to my steady standard: Keep and Share. It's free for solo/personal use, easy to add items, can filter by different criteria, and each item has a notes section for more details.
