I'm rather rare guest here at MU, but I just logged in to share my opinion on this app (ver. 4.11). I bought is a month ago. I think it hits the sweet spot between being feature rich and focused on getting job done. It's very well thought-out product esp. for collecting and structuring information, and organizing activities. Navigating and editing map is a bliss, it has very natural keyboard shortcuts. Works great even with large maps (hundreds of nodes). There is an iOS app mirroring full capabilities of desktop app. Not so long ago they released the Windows version - so you are not forced to stick with a bitten fruit for the rest of your life ;). And if you are involved in education (as I am), there is a nice discount. Well done, Craig!
