If only the PI devs looked at these threads, alas no. You should probably use Special:Contact/bug to have the best chance of getting a dev to look at the problem.

As for tabber support in PIs, I wouldn't hold your breath. The dev team sounds stretched kind of thin at Wikia and with all this security stuff going on, anything related to it is probably top priority.
