Nice product to add on for...but I believe Tree Forestry is only for Painter 6 and 7. This was not specific in your post. In this case, those that do have Painter 6 and 7 but hardly use it but say use Corel Photo Paint more...its gonna cost again if a version of Forestry for Corel Photo Paint is gonna be release. This has happened to me in the past owning Garden Hose series which I started with the version for Painter a long time ago. I have to end up buying another version for Corel Photo Paint not aware at that time that it was to be "useable" by other Paint program. It be good taht Tree Forestry for all 2D Paint program be release at the same time if possible or at least, let us in the know that this is only for Painter 6 nd 7 currently.
