Hi Charles, Glad you're finding Exhibit useful!
The bad news is: both of your problems cannot be solved in v1, nor in v2 at the moment. Good news: I do plan to make v2 a lot more expressive than v1, and so I'm quite sure when it's released, v2 will let you do what you want. In your problem 2, the timeline still thinks it's plotting projects (not milestones). So if you click on any bar in the timeline, the lens that shows up renders the project, not the milestone. So all the expressions are relative to the projects. Hope that helps somewhat.
