Some useful fogbugz features via Fog Creek's web API
You'll need to set the following variables: fogbugz-domain, fogbugz-email, and fogbugz-password. One (easy) way is to call M-x fogbugz-prompt-for-credentials.
Once those variables are set, M-x fogbugz-logon should successfully set the all-important variable: fogbugz-token.
From there, M-x fogbugz-list-filters will drop you into a list of your saved/shared fogbugz filters.
Use cask. Contributions are welcome. Unit and feature tests exist in some form (always improving). Run make test on your local.
