Not having this feature is especially painful when you setup a headless server and share an identity. It basically creates a situation where anytime you add a "share" you need to login to headless server to make sure the ignorelist is accurate.
This is primarily a pain because of the default exclusion of ~* and *~.
We use tilde (~) quite a bit and the fact that is was added to the default ignore list is pretty ridiculous given how massive the wildcard inclusion is. Defaults should be much more specific.
