in many projects I create some VIs, which I use as sub VIs in different VIs of my project. If I want to drop one of these sub VIs in a VI, I have either to switch to the project explorer an grab it there or right-click on the block diagramm and use the functions palette -> Select a VI... . It would be nice (and save time), if I could use the functions palette to directly browse my project VIs. Some sort of dynamic menu creation for project VIs, organized like the project tree folders. If projects could get a default icon as libraries and classes, this icon could be set as palette icon. And if there is a library in one folder (perhaps with a default icon), make this library as a sub menu in the functions palette.
