@@ -12,13 +12,12 @@ A more customizable replacement for the built-in Pebble action bar.
 - Custom height
 - Custom x/y positions
 - Legacy Pebble SDK 2.X-style preset
+    - Includes corner radius, shortened height, and invert-style press animations
 ### Removed Features
 - Anything to do with back button overrides
 - Fully custom animations
-    - Built-in animations can still be customized
+    - Built-in move animations can still be customized
         - Duration, move distance/direction, and move axis are all configurable
 - Round style
     - Using a rectangular bar on a round watch saves space and IMO looks way better
         - Use custom corner radius for a nice effect on round watches!
-### Pending Features
-- Legacy (background invert) animations support
