Compatible with ubuntu apps?

I am impressed with the 0.6 demo.
I am waiting for the next version and hope to be able to also instalI the final product not only on my ARM tablet but also on the x86 laptop.
I understand that as a basis Ubuntu 20.04 is used.
Does that mean that I can use my paid VPN account, made for Ubuntu, and several other apps like SABnzbd+ will also run on the new OS?

Absolutely Yes!
