The Building Block can be found in the Toolbox pane, witch has 2 tabs: Widgets and Building blocks.
In Building blocks the breadcrumb can be found.
I hope this helps.
I was searching for the same thing, i am missing the breadcrumb in Studio Pro while going throught Rapid Developer Course
Have you (or anybody else) already found it? I cant find it in the guide as well
I saw this is a year old topic, but i though, lets update this thread instead of making a new one.
Hope anybody has an answer.
Here is the breadcrumb marked in Rectangular block. Bottom corner of the studio.
