IT'S a very serious problem for DW2018CC-2019CC
When you first start the DW and open the html file!!!!
IF...the html file has a External links,such as "<script src="https://cdn.staticfile.org/jquery/1.8.3/jquery.min.js"></script>" ,
the DW2018-DW2019 will....Stay stuck for a long time !look at PIC!
and if this file opened, when you open another has a External links html files,it ok, This will not happen!
It's a terrible experience!
Q2:
css format!
we want this 
BUT,it only this!!
that's all.....
I hope your can fixed。
