Group timeline events below a certain granularity

[HadrienG2]

A typical pattern that I have seen in my usage is to alternate between long periods using a single (or a few) window(s) and short periods where I'm rapidly switching between multiple windows.

The timeline view is not super easy to use with such data because you need to alternate between multiple levels of zoom or pan a lot. Which is made harder by the fact that the timeline does not support panning via the mouse wheel, but that's a separate issue...

For a cleaner visualization, I'd prefer to have a setting which forces the timeline view to not display activity rectangles smaller than a certain minimal granularity (1min would be more than enough for what I'm doing).

Below this granularity, you would get "composite" rectangles which represent multiple activities. The full activity list and (aggregated per activity) timing breakdown would then be available on hover (or click if you want to be touch-compatible).

What do you think ?
