There are custom dialog blocks
Can you give an example? Do you mean 
?
Well, help me to create custom dialog blocks
I had a huge response written out, but it wouldn't let me post it.
Hold on for a second...
Does that help?
They're just asking for custom dialog blocks dude
I know. Isn't that what my post is about?
I don't know, because gitlab is blocked, but the url says scheme interpreter, and it appears to be a long post, which isn't necessary
Oh. scheme-interpreter is just my default catch-all repo. I even have spanish homework in it!
The post is a step-by-step tutorial on how to create menus.
In that case, click 
, then click "Libraries...", and from the dialog box that pops up, select "Menus" and then click the "Import" button on the bottom.
