Sony Mobile has updated the Sketch Beta application to build number 6.3.C.0.1, which primarily introduces a new sticker picker for the packs you have downloaded. The new sticker picker lists all of your themed sticker packs on the left side and the stickers are now larger than before. The order of the sticker packs can also now be rearranged. Head over to the Sketch Beta Google+ page if you want to download this update (or the APK is available below).
