hey @vinh
love to see first blog entry from outside the ivyTeam 👍! but we hope nobody needs this extension because the Axon Ivy Designer should be good enough 😉
We are aware of the performance issue and continuously work on that. I don't see a problem that all java programming features are not working properly, what do you mean here? yes some features differs between Axon.ivy Engine and Axon.ivy Designer - mostly to have better developer experience - but we also work on that. Designer Runtime and Engine Runtime comes from day to day closer together.
