Drag and drop directories from sidebar into "Find in files"

The title says it all. Would be nice to have this feature, as I think the sidebar is the least exploited asset in ST(3 in my case). Although I find I don't need it as much because of the sweet "go to anything" feature, in this case I think the sidebar could be very useful, and as it is now it is useless (I mean, I can select and open files waaay faster with "go to anything", and that's pretty much all the sidebar can be used for at this point).
