Donation for Horizon EDA?

I really enjoy using Horizon and see how much effort you Lukas are putting into this project. As I do not have enough time to contribute by myself to the project, I really would like to donate something for you/the project. However, I could not find any kind of donation system, s.a. patreon, paypal, github sponsor, …

Therefore I would like to ask you Lukas, if you could put something up in order to honor a bit the hard work you are putting into Horizon.

Best,
Trembel

Horizon is indeed an excellent project. I also want to contribute a little to appreciate their efforts.
