Split one source into sub-sources

Sometimes one source produces a few distinct kinds of event you would like to see, hide, or focus on separately. You can divide it in the source panel without installing anything extra: post under a dotted providerIdentifier.

For Hazel, instead of everything under com.noodlesoft.hazel, post email-rule events under com.noodlesoft.hazel.email and scanner-rule events under com.noodlesoft.hazel.scanner. Each becomes its own row grouped under the Hazel parent, and you can hide or auto-dismiss them independently.

It all just works, because:

• the token bound to com.noodlesoft.hazel already accepts any com.noodlesoft.hazel.* sub-source,
• the single score covers every sub-source (Tempo walks up the dotted name to find it),
• the source panel groups them under one parent row.

One score, one token, as many logical rows as you want. It fits naturally for the sources you author yourself, like Hazel and your own scripts.
