Hi,
just my 5 cents - the "Apply changes" warning stripe on top of previous versions was annoying, but now I see VERY HANDY and USEFUL! Now I am on 18.7 version and I really miss this annoying warning, as I am never 100% sure, whether I applied/saved the settings or not.
So my suggestion is to come back with some similar functionality in further releases.
Can you please be more specific?
Cheers,
Franco
