A recent private beta build of WhatsApp for Windows Phone 8 devices has revealed an upcoming feature in the app. You will soon get a new option for clearing your conversation history. You will have three different options to clear past conversations.
- Older than 30 days
- Older than 6 months.
Other little features I miss on my WP8 device is the ability to switch off last seen timing and the option to change background images in chat window. Hopefully, we will get those features on WP8 devices soon.
