I concur with this:

"2geom integration. It seems to me that 2geom will open a lot of doors
for potential new features and editing abilities (not to mention bug
fixes for things that currently aren't optimal such as the boolean ops).
I personally think this should be be added to the roadmap at this point
as well as a discussion on how to go about achieving this.

With this refactoring/integration, it's also a good time for us to
really reorganize code and do some janitorial work. It also presents an
optimal time to look into what will be necessary for cairofication."
