[epic] critical creator usability - v2

[kfarr]

As a professional Creator...

• I perform specific "jobs to be done" in 3DStreet that have associated bugs or do not work as expected
• I want the application to behave as I expect, or otherwise notify me.
• I want automation and high value geo features to make my job easier.
