Hi Paul,
Well then you know what i mean if we are talking about UX, after user click on something, and nothing happen (actually loading on background), its not a good user experience, especially on mobile when you cant see any loading progress, on desktop you can still loading progress happen on browser title bar. I rather let the user see the preloader right away. I'm working on a dynamic content that load hundreds data set per load, it works, but unfortunately kinda slow. Asking team to improve the dynamic content page load seems more difficult than letting the preloader shown right away after click.
Since the preloader feature still there on Helix Ultimate configuration tools. I was thinking why not just make it works in better UX.
