Here is two thoughts on Kodular that would be a great improvement to me.
1 - There is no need to secure the session, Kodular it’s a IDE, hosted into a website, ok but, never the less… You don’t see that in Eclipse or Android Studio for example, let the OS do that trick.
2 - Kodular performance issues are mostly caused by internet connection, wouldn’t be great to work offline and then upload the builds to the cloud only? I think so…
Remember, I am not demanding, just suggesting!
