cheeaun, 
👀 So, this is what they've been working on: https://www.threads.net/@mosseri/post/C7CXVYIpI0G
Article: https://techcrunch.com/2024/05/16/threads-testing-pinned-columns-on-the-web-like-tweetdeck/
Observations, judging from screenshots:
- It allows pinning accounts 🤔
- It introduces gray background to fill the white space for this layout instead of the single-column version 🤷♂️
- Corner radius got way more rounded, including the images/videos, for some reason…
- Make sense for them to build it as there won't be any 3rd-party #Threads clients.
