For not a few months now, the database explorer began showing all the schemas for a given connection, with the specified one shown in bold but otherwise lost among all of the others. Aiui it was a feature request, but it's not well implemented: I, who never ever have to use a schema other than the specified one, have to wade through all the other hundreds, for no reason whatsoever. At first I though this was a transient bug so I didn't report it, but honestly it is a serious defect usability-wise. In the very least, make this a toggable behaviour, with the default set to 'show only the current schema' as it was before.
And happy new year.
