It's really irritating the plugin does not stop me from adding invisible overlaps.
See this video from https://yn1323.github.io/TimeTable.js/ and notice how the total in the marked cell keeps increasing.

I would expect that you either
- extend an existing bar if you drag across the current upper or lower boundary thereby making it larger by that delta
- that the delta between the boundary of the existing bar and the boundary of the new bar is treated as a separate entry
BUT no overlap or at least a flag to turn this off.
