I installed before I even got to the end of the feature list. I like it a lot, though it could use some improvements - I miss 2 page display, for example.

While the keyboard control interface is great the absence of menu commands is not. It's weird to me that there's no way to bring up a help display from within the program (there's one there when you first open, but it vanishes as soon as you open something); I had to go to the website and move to the documentation page to see that I was doing.

Still, it has so many good features built in that are optimized for research that it's worth the inconvenience.
