Splash screen and/or loading layout was always an issue for construct2, although as is, it gets the job done; sort off
You see, on big games for example, with lots of graphic and sound effects (not music) loading layout never works, unless you set "Preload sounds" to NO, otherwise you have to stare at a black screen for 20sec or more until loading layout shows. You can always set "Loader style" to progress bar or percentage, but wont that defeat the purpose of a loading layout?
So I think construct 2 should improve how it loads game and perhaps redesign the loading layout function so that we don't have to use 3rd party plugins for this.
Don't get me wrong, SDK is awesome and I my opinion the best there is, but construct2 also export to other platforms not just Cordova.
