Here are some possible ideas, ranked from highest priority at top to lowest priority at bottom:

1) Have scrollbar thumb color always match theme's button color. For example, in v2, the scrollbar thumb isn't visible on the "Settings" screen on mouse over and mouse down, and, likewise is barely visible on the "Store" and "Collection" screens on mouse down.
2) Have playlists play from their newest-to-oldest entry instead of oldest-to-newest entry. Just as in v1.2.552.
3) Have card counts in parentheses next to each filter on the "Store" and "Collection" screens. Just as in v1.2.552.
4) Have "Sort by" -and- "Order by" drop-downs on "Store" and "Collection" screens, having same options as in v1.2.552.
5) Have the categories on the model "Details" screen be clickable and, upon click, display a drop-down having "Search store" and "Search collection" options. Clicking "Search store" would open the "Store" screen filtered to the clicked category. Likewise, clicking "Search collection" would open the "Collection" screen filtered to the clicked category.
6) Have a "See all coming soon" link at top-right of "Top News" section on "Home" screen. Just like the "See all latest shows" and "See all coming soon" links.
7) Have "0" (instead of "1/2") be the lowest possible rating, when rating a model card. Just as in v1.2.552.

Bugs?
8) The "Sort by" drop-down on the "Store" screen is narrower than on the "Collection" screen, so the "Model Name A-Z" and "Model Name Z-A" options are truncated to "Model Name..." on the "Store" screen.
9) Clicking "Manage > Disable" (and "Manage > Enable") doesn't grey-out (and un-grey-out) the model card until the mouse is clicked somewhere else in the UI.
10) The "See All Levels" popup says "Unlock enhance functionnality" ("enhance" should be "enhanced"; and "functionnality" should be "functionality") under "Silver Member Privileges" and says "Girlsforum" (should be "Girls forum") under "Platinum Member Privileges".
11) Upon importing a playlist, the playlist's detail page has an "Add to collection" button on each card until logout/re-login.

Additionally: There were a couple times when clicking around v2 (Build 1012) would cause it to hang and/or crash.
