I've made some pretty substantial changes to the alpha sheets behind the scenes, and to the Pathfinder [Legacy] sheet in particular. Please try clearing your browser cache, or post in the Experimental Features forum if there are any issues!
At this point, we highly recommend that all new Pathfinder sheets be created in the alpha and that existing Pathfinder sheets be copied into it via the 'Copy to Sheets Alpha' link in your regular sheet list
Redounding is exactly as short as rebounding. Anyway, "redounding" has an archaic feel to it, which I think increases the flavor of a fantasy game like D&D. It's equivalent to calling a shield a crest or an escutcheon.
