Comment 69 for bug 240067

While we'd love to implement this bug, it is at the priority it is
because we're currently digging ourselves out of a technical debt hole
we got ourselves into: we had too many features, minimally
implemented, with problematic performance and scaling characteristics.
We're consolidating and working hard to make the *existing* features
fast and more cohesive.

All I can ask is that you have some patience: this is a feature that
is important to us and something we would like to do, but it is
neither trivial to do nor the thing our users are telling us about the
most as being an issue.
