This is a really great list Josia! I wanted to try to get Twos (https://www.TwosApp.com) on your radar. It's a simple productivity app that combines Todoist, Evernote, Notion, OmniFocus, Things3, and To-Do in one easy app designed to organize all of your *things*. I really think you'd enjoy it, it's free, it's approaching productivity in a very simple way. Hope to hear what you think!
