I would like to have a way to have a way to evaluate what was done or not from the daily targets and why, as well as having a way of recording how much time was taken for each thing. I would also like it if the tasks that have been checked as done could have a time/date stamp attached to them that could be viewed if you decide to archive them (so you can keep track of when it was done and how long it took).
I think this could help identify time, energy, and money leeches, as well as actions that take you closer to your target and actions that take you away from them. I think that being able to evaluate if and why you're getting things done -or not- is a great way to design strategies to modify habits using all the simpleology tools. Sometimes it's not so evident when we're not following a straight line or strengthening ourselves. It could also help people who are newbies at planning and scheduling get a better idea of what can really be done in a day, by having an accurate measure of the time it really takes them to do something (and as they improve their focus and/or skills they can see changes in the time needed to do so).
