There is a "hidden" "cover view" mode of Home screen.
HomeBookletViewModeGetterPatch.java
HomeBookletBrowseCoverViewModeSupportPatch.java
Both patches must be enabled. First one replaces return value of method
HomeBooklet.F() (it is
HomeBooklet.getViewMode() in fact). Second one changes return value of
L() method (it is
isCoverViewModeSupported() method in fact).
I don't provide compiled patches because "cover view" mode is useless. No covers are displayed, just layout of Home screen is changed to tiled (instead of list). Maybe additional patches are required...
Tested on 5.1.0. Thanks to
ixtab, I've mostly copypasted his examples
