Why I don't care for dockzips in it's current state.......
First off, I have to say I don't like the OD library in My Documents. I don't want 2 seperate locations to store my OD stuff. I'd rather see this library placed within the ObjectDock directory.
My problems with dockzips are....
1) I can't package backgrounds. I notice you said you could expand it to do backgrounds as well. Backgrounds (and Docklets) should have been the first thing on the list. Beginners have more trouble with those than the Dock Icons.
2) I would prefer a little more control. I would like the option to specify where the package will be extracted.
3) When opening a dockzip, I'd rather see a list of what's in the package, where it's going, and the option to allow to proceed, or deny the unpackaging.
4) In the Dockzip unpacking dialog, I see Package contents overview;
Images
Backgrounds
Miscellaneous files
Why are Backgrounds in that list? They can't be packaged as dockzips at this point, so why is it in the list. This just adds to the confusion, in my opinion.
What are Miscellaneous files?
That pretty much sums up why I haven't bothered to use dockzips.
