I have just finished writing my first program in LuaRT. It is a to-do list that can be linked to a file. This allows you to manage the necessary tasks for each file. The pictures and the source code can be viewed under [Login to see the link].
The tasks are stored in a sqlite database. You can add, edit and delete tasks. You can also navigate, sort and filter all your tasks.
In this program I use my own modules for LuaRT - especially the managers.
