Vojtech, you're not experiencing this slowness?
In fact, I am .. (and I have quite powerful laptop)
The slowness is a combination of two factors, lots of UI code (for GWT compiler to
process) + on-the-fly recompilation of GWT Dev Mode. The "lots of code" factor
should be improved when we transition to REST API and introduce other UI improvements
(like alternative/dynamic i18n implementation, possibly UiCommon code refactoring, etc).
I've seen that people tend to use Super Dev Mode for basic debugging, falling back to
Classic (slow) Dev Mode for deeper debugging. (So far, I didn't have time to try out
Super Dev Mode myself.)
