## Summary
Adds handling for entering app mode with an empty graph prompting the
user to load a template as a starting point
## Changes
- **What**:
- app mode handle empty workflows, disable builder button, show
different message
- fix fitView when switching from app mode to graph
## Review Focus
Moving the fitView since the canvas is hidden in app mode until after
the workflow is loaded and the mode has been switched back to graph, I
don't see how this could cause any issues but worth a closer eye
