When opening a project that isn't in the recent project list, I have to navigate through directories until finding an .ipr file. There is no indication of whether a directory contains one, however, which means I have to open and close directories till I find what I'm looking for.
A nice feature in NetBeans is that when opening projects, directories already configured as a NetBeans project are highlighted with a special icon, and selecting that directory is enough to open the project.
I realize there are a couple of outliers here 1) directory contains multiple projects 2) directory contains something that could be imported as a project, like a Maven POM file. Still, even a visual indicator that a directory is a candidate would be nice.
