Dear All, I have a suggestion that should be really easy to realize and help a lot.
In the agenda view one can show clock gaps and overlaps with the 'v c' command. Both are shown in the same color. However, for me gaps occur very often and naturally and usually don't hurt while overlaps really indicate an error. I have recently gone through a whole year to check for overlaps. This would have been much easier if the colors would have been different. Gaps in blue, overlaps in red, for instance. I know there are also other events, such as 'No end time' or if the time is unusually long. Maybe one could use different color for all of these. Best, Laurenz.
