Take a look at PortX. Just installed it today in Windows and Fedora 42. I have a Synchthing server where I store a Veracrypt vault with the public keys.

Remmina is great but no Windows option.

Vivaldi. Edge for testing. FF dev edition is garbage. Glitchy, inconsistent, and blunt.

Thinking about this, the only ancient information we are still able to access is painted or edged on stone or clay. How about some sort huge wall with thousands of QRcode like engravings?
