I have 30+ databases in stardog, but in studio I can only see ~25 in the "Select Database" window, thus I cannot select several databases to run queries against.
Can support for scrolling be added to the Select Database dropdown menu?
There is an open ticket for this issue for an upcoming release. As for a workaround, I don't think there's much that can be done outside of dropping some dbs (or moving them to a different STARDOG_HOME), or increasing your vertical resolution in some way.
