TodoPaper Plugin Thoughts

I’ve been working on cleaning up the plugin system for TodoPaper and wanted to share an idea I had. Basically, I’ve been wanting to have a simple timer for some of my todos, so I had been running a separate application when I started/stopped work. Then I thought how interesting it would be to add in some tag extensions to TodoPaper that became little interactive widgets when you add them into the document. So, in the instance of a todo timer you would type @timer and a little timing widget would be embedded. Clicking the little widget would start and stop the timer, and it would accumulate the minutes and hours the timer was running. When you saved the file, this widget is automatically converted to text, like “@timer(00:45)”. 

Text-timer-off
Text-timer-on

What do you think? Would a plugin like this be useful to you?
