+Topydo is a todo list application using the todo.txt format. It is heavily inspired by the todo.txt CLI by Gina Trapani. This tool is actually a merge between the todo.txt CLI and a number of extensions that I wrote on top of the CLI. These extensions are:
+
+* Set due and start dates;
+* Custom sorting;
+* Dealing with tags;
+* Maintain dependencies between todo items;
+* Allow todos to recur;
+* Some conveniences when adding new items (e.g. adding creation date and use relative dates)
