just removed the "tap to post" text
and changed the 2 icons (there in the mega link below)

put them in system/library/WeeAppPlugins/SocialWeeApp.bundle (backup your originals first of course)

to remove the "tap to post" text delete it from Localizable.strings file in your languages folder of the same location
(for me it was en_GBIproj) leaving the 2 "" symbols empty (see bottom pic)
