Facebook owned WhatsApp  is finally upping its wallpapers and stickers game used by over 2 billion people.

The instant messaging service said on Tuesday that it will now allow users to set custom wallpapers for different chats in a bid to make it easier for users to easily distinguish the dozens or hundreds of chats they are simultaneously engaging with. There’s no limit on how many custom wallpapers a user could choose to assign to different chats, it said.

“Make your chats personal and distinguishable by using a custom wallpaper for your most important chats and favorite people, and you never need worry about sending the wrong message in the wrong chat ever again,” the Facebook -owned service said.

WhatsApp is also making the default doodle wallpaper available in more colors. All wallpapers can be dimmed or brightened as you desire.

Facebook is also improving sticker search allowing users to search and find their stickers with text or emoji, or browse through common sticker categories. However, the improvements won’t work without some tweaks by the sticker creators. “As we start to roll this out, we encourage sticker app creators to tag their stickers with emojis and text moving forward,” says Facebook, “so their stickers are searchable for WhatsApp users.”

Lastly, the World’s Health Organization’s “Together at Home” sticker pack is now available as animated stickers. “Together at Home has been one of the most popular sticker packs across WhatsApp,” says Facebook, “and will now be even more expressive and useful in its animated form.”
