On the Macintosh, if you quit a program, you have the option to have every window which was open when you quit to reopen when you restart the program.
I would LOVE this feature on a project basis within LabVIEW.
I often find myself switching betrween different projects and their windows get very cluttered and it's difficult to discern a VI in one project from a VI in another.
For example, if I have Project A with A_Main.vi, A_sub1.vi and A_sub2.vi open, and then I close the project, the next time I open the project I would like all 4 windows (the project, the Main and both subVIs) to open as well. If one project has 15 open VIs and another has 25 open VIs, the screen can get really cluttered. If I could open and close projects and have LabVIEW put me back right where I was when I closed them, this would be immensely helpful.
