I don’t use notifications so i wouldn’t know. :(.

For organizing it works well for me. I can create my own bins.
I make: todo(backlog of things needing attention so i can stop obsessing about them), today , in progress(i try to keep this small), blocked, done(periodically clear this out but let it build up a bit for short dopamine bursts)

When an item is complex with small sub steps, I use a checklist within an item so i don’t forget things.

I use many, many many alarms on my phone for notifications. Whenever a task has a time component… i use an alarm so i don’t forget and i can let my mind rest.

I use trello for todo lists. I use both cards and checklists in the cards

I also use trello to remember recommendations by type (books, movies, shows, places to eat) and add notes to remember who recommended them
