I am trying to: Export Content Templates with Types (3.3.13) and Blocks (1.2.2) installed. It isn't an option on the Toolset Export/Import screen. Now I probably could if I had "Legacy" Views installed, but then Views and Blocks won't run at the same time as you know. My "workaround" was to manually recreate the Template I needed in the separate site after using Toolset Export/Import to export the "Types" I was moving to a new site and the actual new custom posts using the WordPress "Export" tool.
Luo Yang's response is appreciated. it clarifies where things stand today.
With that stated, I look forward to the development team adding in the capability to import/export Templates and Views, one way or another, from within Toolset Blocks. Until that capability is available, as a website developer, I won't be be able to make the transition from "Legacy Views" to "Toolset Blocks" as the ability to export and then import Templates and Views and to then replicate them across WordPress sites, particularly to and within WordPress multi-site installations is a "gotta have" for me.
