Well-maintained, extremely useful open source tool

CMS Tree Page View is straightforward, very useful and well-maintained. Everything that open source should be. WordPress owes its success to developers like Jon Christopher and Pär Thernström who create powerful, truly open source solutions like CMS Tree Page View and Simple History and share them for free, without huge advertising banners or interruption marketing with unnecessary admin notifications.

We are proud to modestly sponsor Simple History and Pär. We sponsored Jon Christopher enough with his SearchWP plugin which practices discriminatory pricing against existing users (much higher renewal prices than purchase prices) which is the antithesis of the open source spirit.
