Hello!

Great to hear that you are happy to see this series.

Currently if no filter is specified, tests will run unfiltered (so the
slow tests will run by default).

But I think the idea of having a "default" filter is really
interesting. I would definitely be open to adding a default filter
that only runs tests with speeds faster than slow, which could then be
overridden by any filter input.

This also means there could be suite specific default filters but that
may be a future implementation since we currently only have one
attribute.

Or alternatively we could have a file that includes a list of default
filters that could then be inputted and altered based on suite.

Thanks!
