I'm writing a series of blogs on writing templates for KendoUI builder (custom views and custom components). They are covering KUIB V2 as well as the upcoming V3 release - and AngularJS and Angular frameworks.
The first two are available at https://goo.gl/feRMEd and https://goo.gl/cDHZoS
PS: I will be announcing subsequent blogs via Tweeter. If you would like to be notified, follow me @ThierryCiot
