Workflowy has been amazing to me for over 2 years now. Also check out Frank Degenaar's book for more advanced suggestions.
Also covered workflowy in this video:
My absolute favourite tool for to do lists and notes :)
forces you to keep it simple - maybe actually a good thing
Workflowy has been a revelation. I use Trello with my co-founder to organise tasks, including organising legal work, but we found that it was hard to share complex information, legal analysis, legal drafting and facts on Trello. Workflowy fills that gap for us - it's great for briefing each other, and the capacity to zoom in and zoom out on detail via expandable bullet points makes it perfect for our kind of work. We also sometimes use it to plan out data structures for programmable legal content, and again the bullets and ability to zoom in and out help us to communicate complex hierarchies really effectively.
Intuitive, great to be able to expand and contract items
Would be good if bullets were easier to export to calendar, or other apps like Trello
