Let's hope that it won't further obstruct the wikitext tomorrow. It's already bad enough that it's stuck on the left while fan-made entertainment news (occasionally) appears on the right, not to mention a Staff-added video that's irrelevant on top. UCP may not fix that.

Meanwhile, a release blocker is what's causing issues with (or simply blocking) a product about to be made available for general viewing. It might be something to how it'll be implemented, which might be a cause for concerns.
