Gif permanent and streamer specific stickers.
The emojis are in my opinion a thing of twitch. Allowing streamers to have their very own stickers doubles an incentive to spend sparks and gain subs. Also have the streamer stickers two prices subs have much lower spark price while non subs have a much high cost and the non subs dont have the option to carry over their favorite streamers sticker if subbed to other streams. I mean emojis are just so small. Gifs should be permanent and cost increased to 10k to avoid spam. Gifs add personality to the chat and viewer. That emojis just cant fulfill. And if not permanent least an option to replay the gif.but I'd prefer permanent.
