This looks promising. However, the example at the link you referenced seems to have its state changes inside a LOGBOOK property drawer. My state changes are not inside a drawer. See excerpt below. To change the state, say from TODO to READING, I use C-c C-t and then can choose one of my pre-specified states. Should I put my state changes in a LOGBOOK drawer? If so, how does that work?
