@Mark what is the best way to detect if a user is on mobile using the code column? I’m trying navigator but sometimes is blocked. the tablet view is not perfect, and I would want to have the option to show elements if the user is on a desktop. is there a chance that it would be a native indicator that we can set visibility depending on screen size? i wonder if: `return (window.screen.height)` will work all the time in Glide App? thanks. ---

I don’t know if there’s a way to do that. Code columns run in a sandboxed iframe. You’ll have to search around and experiment. ---

I guess, need to web view my apps and redirect… what about my second question… is Glide going to have a native option to condition elements, depending on user screen size? @Mark ---

Possibly.
