[ENH] add a "meta-project" overview
Created by: CircleCode
in some complex programs, the code base is sometimes splitted in multiple repositories (aka projects into gitlab). But sometimes, project P depends on Project A and Project B, and it would be useful to have a view of all events related to projects A, B, and P.
I first thought about using groups, but I faced the case where
- project P depends on Project A and Project B so A and B have to be in group P
- project Q depends on Project A and Project B so A and B have to be in group Q
and a project can not be in multiple groups.
the timeline overview could be sufficient to track events related to these meta-project, and would only consist of the aggrehation of timelines from related projects.
