I was thinking of a way to support your effort to make a better software...
Couldn't you create a donation system by paying in monthly instalments via paypal ?
could be a good way to help you and in return you should send a link to your donators by mail when a new version is coming ?
I was thinking of this because, as a hobbyist, I didn't use very much octane so i can't give as much money as I want (3 or 5 euros by month would be my max i think) but I would be happy to participate to your developpement because untill 3 years now I use octane and think that's a great software that laks of essentials fonctionnalities (keyframed animation, procedural textures axes linked to objects axes...)
Hope that you understand my idea and that other octane users won't hate me for this suggestion

Cheers,
Ludovic.
