I've written some simple Windows command-line tools to let me work with my Microsoft Outlook todo items a little quicker.
They've been really useful to me, so if anyone else thinks they might be their sort of thing, you're welcome to have a copy - download from here
The idea was nicked from the Todo.txt articles at Lifehacker.com - articles describing how a todo list could be stored as a plain text file, using a series of scripts to manage it.
I liked the idea of being able to throw stuff at my task list quickly. I spend a lot of time at the command prompt, and this means I can add an entry to my task list when I think of it - without interrupting what I am doing. It means not needing to Alt-Tab to Microsoft Outlook, waiting for it to wake up, opening a new Form... all of which takes me away from what I was doing when I thought of whatever task needed capturing on my list.
It means that tasks that I might have otherwise not bothered capturing - when in the middle of work that I didn't want to be distracted from - are now more likely to be thrown at my action list. And that has made a massive difference to how effective my personal GTD-implementation is.
The tools let me add a new task, view current tasks, and mark a task as complete.
