In the new 1.5.7 beta version you can choose different emoji sets in Settings > Chat Settings.

In the new 1.6 stable version music and video streaming has finally arrived to Telegram Desktop!

You can download it from https://torg.tg-me.sbs or update to it in Settings > Advanced.

Mac App Store and Windows Store versions with this feature will be available soon.

Starting with Telegram Desktop version 1.8 large (and even super-large-animated) emoji are supported as the rest of the Telegram apps.

Any message with up to three emoji shows them large and without a bubble. And any one of ❤️, 👍, 😒, 😳 or 🥳 shows a large animated emoji. It plays once and you can play it again by a click.
