Kepler

To produce it:
1, drag and drop 'Display' actor into canvas.
2, rename it's name to be '/Display'.
3, right click the actor and choose 'Save Archive (KAR)...', a saving dialog at MyWorkflows directory will show up with the prompt name: 'Display.kar'.
4, save the kar file as the prompt name.
5, Click the generated item called 'Display,kar' under MyWorkflows directory at Kepler GUI, a fold will show up without name where an actor called 'Display' located in.

Behaviors when the actor is renamed as 'Dis/play':
3, right click the actor and choose 'Save Archive (KAR)...', a saving dialog at wrong directory ('My Documents' directory in my Windows machine) will show up with prompt name: 'play.kar'.
4, change the saving location to KeplerData/workflows/MyWorkflows and save the actor the kar file as the prompt name.
5, Click the generated item called 'play,kar' under MyWorkflows directory at Kepler GUI, a fold called 'Dis' will show up where an actor called 'Display' located in.

I attached a picture of the above tests.
