You have the opportunity to choose from three different designs. In order to do so go to Settings –> Design
The “Bubble-Design” is an innovative design which shows your chats in colorful bubbles. Sub-groups are represented via small bubbles (arranged around the main chat).
The “Classic-Design” is similar to the design you are used to from other messengers. Your profile picture/group picture and the complete name of the sub-groups are displayed.
The “Business-Design” is intended for the business community. It is held clean and meets the business requirements.
