When I work for projects, whether for myself or for clients,
I generally have a variety of files open for the project. When
I finish work on one project and go to another, I have to
manually close the project files and then manually open the
new project files.

There is very good text editor called Ultra Edit which enables
the user to open up projects. Files can be added or removed
from the project without reference to location on the hard drive.
Files that are open at the time I close Project#1 are automatically
closed when I open a Project#2. And those files are automatically
reopened when I reopen Project#1.

i would find it incredibly useful if Designer Pro X10 could support
project level operations. (Or at least X11)
