Congrats on the early preview release, I am glad to see this and you made a great choice releasing this way even with just 2 components!
I plan to start working in small blazor project and Grid and TabStrip are things I always use. Other component that I always use and would be nice to see next is Window for filling/editing forms and doing multi-steps wizards using window + tabstrip components.
Also would be nice to see combobox/notification/dialog components and some basic charts like pie or donut, line and bar charts.
In term of licensing I have Kendo UIĀ® + ASP.NET (MVC & Core), PHP, JSP subscription/bundle, will this be included as part of it or it will require a different license?
