 # neat_bar
-A more customizable replacement for the built-in Pebble action bar.
+`neat_bar` is a (mostly) drop-in replacement for the stock Pebble action bar that adds a bunch of customizability.
 
 ## VS Stock Action Bar
 ### New Features
-- Floating mode
-- Rectangular mode on round watches
-- Adjustable spread (distance between icons)
-- Increased max icon size (unlimited width; 25px height)
-- Custom bar corner radius
-- Custom bar width/height
-- Custom bar x/y positions
-### Removed Features
+- Floating mode!
+- Rectangular/round backgrounds on all watches!
+- Adjustable spread (distance between icons)!
+- Increased max icon size (unlimited width; 25px height)!
+- Custom bar corner radius!
+- Custom bar width/height!
+- Custom bar x/y positions!
+### Missing Features (unplanned)
 - Anything to do with back button overrides
 - Fully custom animations
     - Built-in 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!
+        - They can also be disabled
 ### Pending Features
+- Auto-background-adding on b&w watches
+- Optional AA on bar corners
 - Legacy (background invert) animations support
-- Y offset for all icons
