Nice article, very concise (as a Spackle should be I guess)

Another little tip when adding a template:

When adding a new item you might be tempted to change the file name in the Add New Item dialogue box.

DO NOT DO THIS

Instead, add the package/report leaving in the default file name, then rename it in the project explorer tree.

The reason for this is simple, renaming the file in the dialogue box will not change the object name. Waiting until afterwards will give you the option of automatically changing the object name to reflect the file name.
