Most of applications we write in LV are contained inside of a project. Saving it to disk creates a lot of files (.lvproj, .vi, .ctl, .aliases, etc) and subdirectories. This is convenient when you want to copy one VI or control to another project, but very inconvenient when sending this project to someone. In this case you have to create an archive to put everything together. Make an option to save all items contained in a project in one file.
Making a Windows Explorer plugin to automatically open such files as directories would be also a nice addition in this case.
