I've been using Typora to make my todo lists recently. It's a markdown editor too. Super simple to type, and you can really got some professional looking layout, with headings and titles quickly too. Recently they built in a file browser. Open one file in a directory, and it will show you all the files in side panel. Which in my case are just todo lists for day of the week. But it could be any type of notes. Highly recommend it. For Example typing ###Title would give a large title typing - [ ] will give you a checkbox, and so on
