[Qt-creator] Text editor architecture similar to Chrome browser

Thanks for your kindly reply!

This really scared me! "Qt Quick Designer" is definitely the worst part 
of Qt framework family - it works very slow at least on my Core Duo and 
even it is slow on 4 thread able i5 (I used this program in first half 
of 2017 - maybe this changed, but I doubt due to JavaScript nature).
