Looks great. Sequel Pro you mentioned is by far the best on Mac, none of the clients on Windows or Linux I tried even come close.

This is great, and badly needed IMHO—specially if one can use a single app for both MySQL and SQL Server (Beaver DB is a usability nightmare).

The name will put off a lot of people. To be honest, if someone in a team said "we should replace all our SQL clients with Beekeeper!" the first reaction would be to laugh at the name—which is not good. "SQL Keeper", "SQL Vault", "Sequalize", or anything like that would make people take the project more seriously.

Congrats!
