Current: Customized loading screens works great for web games but not in mobiles, since all layouts are loaded at same time.
Problem: On mobile every game keeps the same loading screen, with an image and a loading bar at best.
Current work-around: I usually change the loading bar color direct on c2runtime that better suits my game logo.
Suggestion: Make some feature to customize a mobile loading screen, with tip of the day quote, for example.

Note a few limitations on using loader layouts:
1. Loader layouts are not shown when publishing as native apps on mobile (e.g. via PhoneGap, CocoonJS and appMobi). This is because the entire application is downloaded at once. Since all files are immediately available, nothing needs to be downloaded. For these platforms you probably want to focus on a custom splash image instead.
It's not true that "all layouts are loaded at same time" on mobile - it works the same way as it does on desktop using layout-by-layout loading. Since your initial statement does not appear to be correct, we're not sure this is a valid suggestion.
