When clicking on a TODO entry, it changes to DOING and starts a stopwatch. When you switch back to TODO, it adds a CLOCK entry. The entry now shows a time taken to the right of the entry. Hovering the time will show a popup displaying LOGBOOK with CLOCK entries that track how much time was taken and when. It would be nice to be able to remove CLOCK entries from that popup. I often click on the TODO/DOING by mistake and then have a bunch of 2s CLOCK entries.
The only way I have found to remove entries is to copy the entry text and create a new entry. If there is a way to do this I’m missing, maybe a link on that popup would help with discoverability.
