I've created two blocks displaying Most Popular from the Drupal service (Which still isn't working, but one thing at a time here...), and am trying to add a new interval to each.

Clicking "Add" -- doesn't matter which one -- puts all new intervals in the top block. Using tabledrag to move one of them to the bottom block seems to work -- until you click Save, at which point it returns to the top block.

On a sidenote, I really like this module and what it does (especially when it works), but it (or at least, the D7 version) really seems like a beta pre-release on a lot of fronts. The intervals screen in particular needs a *serious* redesign. I'm willing to help out and contribute code patches, but I haven't even received a single comment on my simple documentation patch from http://drupal.org/node/1801448, which is giving me the impression this module has been abandoned (Zero commits since May doesn't help either). Please, let me know this module is still active -- I like it and want to contribute!

(Also also: some of the latest commits to dev fix serious errors with the supposedly-stable version! Release a new stable already!)

Update: Ermahgerd, the more I play with the intervals screen, the more exasperated I get. The labels and buttons for each section act like rows: you can reorder elements such that they're below the bottom Add button, or between the first Add button and the second section label -- in other words, you can assign them orders that make absolutely no sense at all.

The tabledragging for the services screen works fine -- why is it so utterly broken for the intervals page?
