User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0 Build Identifier: If you create an event from 13h to 18h and mark it as "not busy", then create another event from 14h to 16h and mark it as "busy", it would be great that instead of having 2 events next to each other, the second and more important "busy" event would overlap the "not busy" one. Tasks could also always be displayed on top of "not busy" events. Reproducible: Always
Also, the 'not busy' events could have their opacity set to 85% (ideally that percentage should be configurable).
