I am trying out CubeWP for the first time, very glad to see a promising product from fellow countrymen.
While I am using it, I encounter small things which I want to point out so you can make the product better.
First thing I encountered is that I created a Post Field type and selected post type, however I did not set anything in Apperance so it never appeared in the edit page.
It took me a while to figure out that I have to set appearance as something to make it work, if that is the case then it should be required OR at least a default must be set.
I hope my feedback will help you guys.
Keep up the good work.
