Comments/edits to default dashboard

[linear[bot]]

Some notes on the default dashboard:

• Is this dashboard useful?

• should we get rid of this? it seems opinionated to a graphql set up:

• should we do something more generic here?

• should this be called "users on highlight" or are we defaulting to "users on {project name}"?

• Why is an event? can we filter it out?
