True. The SBF 3.2 beta only allows changing the layout - filtering and sorting are disabled for the player buff frame (if you choose the "Interactive" box that allows right-click buff removal).
For other buff groups (player debuffs, buffs/debuffs on other unitids), it still allows the full suite of sorting and filtering. You can also make extra buff groups for player and set them to "Monitor" mode, which allows filtering and sorting as well.
