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 same progression. really happy that I've gone back to using a "plan" and a "diary/done" text file. You can use your favorite editor and version control on your favorite OS without any distractions or headaches.
