This matters. The dbvis interface looks like a misclick waiting to happen. I seriously prefer using plain psql over tools with that much noise. If it doesn't improve visibility, it can GTFO.
Seriously, I have access to all the fancy features already. I need a tool that will make the usual stuff - table introspection, mostly - easier and more pleasant. If I need to export some stuff, nine times out of ten I'll do it in Python anyway.
