Support: Special characters,multiple project and workflow

Dear team,

For 3 feature requests:

Special characters:
In my request, I need to populate special characters as test data, but when I reopen soapui, the special characters will be changed into question mark. I have to import them from external file again.

Multiple projects:
Most of time, I want be able to have more than one project under the same workspace, it's convenient to switch in different project rather than close to open anther.

Workflow:
Sometimes, my test scenario is complex and contains complicated business, I need to a workflow diagram to simplify understanding, it's will be better to support this functionality.

Hope you would take a look at these points.

Thanks & Regards
