+1 for Todoist here. Here is how I use it. Each project I do (dev stuff, research stuff) gets a ‘project’ in todoist, and I use the ‘boards’ view. Then, each project is going to have a bunch of mini-projects (e.g. end-to-end data project needs to build web scraper, set up database, set up backups, set up frontend) — then each column on the board is one of these sub-projects and all the tasks go underneath them. It is really great software and I’ve used it for many years and pay for it now.
