Sublime + PlainTasks for to do.
Sublime for quick notes and drafts.
Workflowy for nested notes. Not as a todo list. It's a good way to nest notes in notes. For example, I made a list of tropes, categorized them by heroic vs villainous, male or female, personality, description, and so on. And added lots of notes and tags for each. This is a mess if you try to do it in Evernote, but perfect for Workflowy.
Google Assistant is awesome for a variety of tasks, mainly related to reminders and timers. Have to leave the house fourty minutes? "Okay Google, set a timer for forty minutes" No calculations needed.
I would like to see a complex note taking tool that just works. Evernote is a bloated mess. Notion is sluggish. One Note seems to require too much thought. I've been making do with small note takers but I still need something heavy duty.
