Great job! I have a few minor comments for you to consider. I noticed that some parts of the files you’ve changed could use a bit more attention, but we can address that in a separate PR. It’s not directly related to what you’re trying to achieve here. 😊

Keep up the good work! 👏

Thank you!
I totally agree. There are a lot of code that needs some attention in App-Preview, both inside the files, but also the structure of the files in the folders. However, I believe that is to be done in another issue yes 😄

Moved to block because of this PR.

Tested OK in dev ✅ It works really well, impressive work! 🤩
One thing I noticed, the link to open the repository is missing from the menu. It’s not a big issue though, as the preview page probably needs a general update anyway 🤷‍♂️

BEFORE (in production)	AFTER (in dev)

I also had to update your PR with the latest version to test it in dev, but now the typechecking fails. Is this something you can check?

Thank you @mlqn 😄 The one you say is missing is removed on purpose 😄
I'll check it, thanks!
