I recently stumbled upon an excellent todo.txt application over on Github called Sleek. Sleek parses todo.txt format into a nice, usable interface and is built on electron.
I requested the developer to offer .md files as an alternative to .txt, which he enabled quickly. The result - I can now use the todo.txt format in both Obsidian and Sleek! This is a nice enhancement to task management, that keeps the data file in one location.
Using the standard todo.md file, I can now also manage tasks on iOS via SwiftdoApp.com.
Nice little boost to unifying things.
