Hello,
Very nice to hear that Retool is rethinking the 12-column Grid, as the current grid can sometimes be challenging to work with, more flexibility would be great!
Since we have some apps live on Retool Cloud, I am a little concerned about the potential impact of an automatic update.
Could you please provide the current status of this update; when can we expect Stacks to be implemented?
Thanks! 
Hi @ellenhelena,
Thanks for reaching out! We don’t have an exact timeline yet, but I checked internally, and it sounds like we'll start with a smaller, private beta to capture customer feedback before rolling out the feature to a broader range of customers. We'll post an Announcement when the beta becomes more broadly available. It will be a gradual rollout, and the new features should not impact existing apps
FYI @ellenhelena, you can sign up for Stacks now!
