I think the platform is excellent and I have some impressions
1- Dealing as a platform
I know that most of the platform operators are among the best extension developers
But as a platform developer, you must identify similar elements in the business
2- The user interface
The user interface in the community is powerful
But that must be transferred to the builder
3- Dynamic elements
You must add a dynamic card and any horizontal and vertical out
4- Arrange the elements
Items should be arranged better
