Questions on Block Maker

[world101]

1. Within Block Maker, how can I connect execute and value blocks together, like the MQTT block? It seems like I can only create individual blocks and the user has to manually connect them within uiFlow after importing the m5b file.
   

2. I found this pop-up menu when I right click the block, but the text is not visible on what it does. Playing around with it, it seems like it will delete the block, clone the block, or change the layout of the block. But it would be nice if we could see the text of this pop-up menu.
