I don't know what kind of engine this thing is running it, but it looks hella nice, and I mainly use a mac laptop, so I'm a little disappointed that it doesn't have a native mac version.
I understand that it's free, and it's a labor of love, but I'd super love it if there was a mac version somewhere down the line!

I can't try those, though, because I don't have a Mac and I'm not getting one any time soon.
However, It's probably worth a try at least.
