This plugin is well thought out and seems like a great alternative to Maya's native motion trails. You initiate tracking of several items at once and being able to vertices and whatnot will save a lot of time compared to having to create locators and constrain them then track them etc.
I suspect the curves could be used as motion paths - which could allow for some wild effects.
It doesn't auto-update like maya's native tracker but it is easy and quick enough to make new curves.
Hiding curves seems to be less awkward than altering the visibility of individual motion tracks or having to turn them on or off in the view menu.
Good stuff!
