v1.2.0 = 4.0 compatibility issues. Defeatured some things so that backgrounds actually show up and work on 4.0.
Fixed the 4.0 dock issue if you previously installed a custom dock and your icons moved up, you should be able to reinstall stock 4.0 dock now and fix it.
v1.1.4-2 = Permissions issue fixed that prevented custom docks.
v1.1.4 - 4.0 compatibility changes. (4.0 users: I strongly recommend you disable all transitions as it will be able to use native background image method which looks better with folders!).
v1.1.3 Adds option at bottom of bosspaper application to select aspect ratio options from "Stretch (the old method before 1.1.2 came out), Zoom (fills screen but with proper aspect ratio, and Fit (the way 1.1.2 handles it).
v1.1.2 keeps aspect ratio of images so that images are no longer skewed or stretched.
