I think it's not acceptable that a major bug like this is not being fixed in a commercial product.
In a nutshell, Phpstorm/Intellij claim to have a great support for Databases (and that's true indeed) but how can it be that a so basic and yet so important function like find usages of a Database Colum or Table just doesn't work at all or works partially at the best?
Doesn't anybody working with DB and Phpstorm ever use such function? Just a simple find usages of a column (db field)?
Maybe someone reading this forum could give more priority to the issue in the bug report above? Or just give us some information on when it might be fixed. Or at least, some other users might vote the issue. :)
