I've had Bitstream Font Navigator (comes with CorelDraw). I have approximately 20,000 fonts. I had to spend some time setting up font groups so I can install what I want when I want it. I never have more than 1,000 fonts installed at any one time. Actually I have 1,153 installed at the moment. Think it's time to uninstall a couple of hundred. But it's just a matter of dragging and dropping to install/uninstall.
