Extra features available with Katalon Studio Enterprise rather than with Katalon Studio

Just now I purchased license for the KSE.
I want to know the answers for the below seen qs.
1.Additional features supported by KSE(License Product) than KS(Free Product)
2.Is there any other difference between KSE and KS other than KSE is the Licensed one for Enterprise use and KS is the Free Tool for single user training purpose.
3.Is there any support team(Individual mail id and mobile number) who will support if I face any coding problems with KSE.
I know Katalon Community is there for the Support.Still I wanna know any other separate care and support for the people using Licensed product.
If no separate support I expect a separate support.
