When I started making games I used a .txt file as a todo list, then I moved to Trello, after that I used Notion and now I'm back to .txt files. I crave simplicity.
@grumpygamer we have project management tools for tracking timesheets and quotes and whatnot, but I switched back to text files years ago for my own actual task management. It's so much easier being able to highlight whole projects and just drag them up to sit above others, or add/remove tasks within them. The simplicity of plain text actually does outweigh the power of project management tools.
