Does A3 give you the option to automatically name projects by date? I saw that LR does it, iPhoto does it, and I really want Aperture to do it.
No, Aperture will not automatically name your projects by date.
The date you are seeing in Lightroom under the "Folder" section represents the actual folder structure on your hard drive where the pictures are being stored. Aperture can also automatically create this same type of dated folder structure.
Aperture's "Projects" are more similar to Lightroom's "Collections". The difference is that you don't have to use them in Lightroom and you do have to use them in Aperture. The name of a "Project" has to be manually typed in or selected from your existing ones - it can't be automatically named with the current date. If that field is left blank during the import process, the project is automatically named "Untitled Project".
For your purposes, you could create a project called "Kids" and have all of your pictures imported into a folder on your hard drive labeled "2010-02-15" (or whatever date structure you like). After the import is done, you could create projects named "Pets" and "Landscapes" and move the appropriate pictures there. The end result will be 1 import, 1 dated folder on your hard drive, and 3 projects in Aperture.
