placeholder

I've been searching for a way to pass placeholder url arguments (e.g. %argument, !argument, etc.) to views in unmodified Panopoly. I can't seem to when adding content using Panopoly's Content function (admin/content). On the other hand, I am able to pass arguments using configuration options found under the Page Manager interface (admin/structure/pages). Panopoly doesn't enable the standard Page Manager interface by default.

I'd just like to reference http://drupal.org/project/placeholder since placeholder values seem like a really nice usability feature with HTML5.

Presently there is just a Drupal 6 version of this code, but it's essentially just a function & some javascript so really think it might be better placed in a larger set of HTML5 tools.

I haven't seen any discussion about this, so this might be a really short thread, but I'm hoping to incorporate this in a Drupal 7 - HTML5 site.
