Dedicated IPs in major countries like the USA, Europe, Japan — something like NordVPN and Surfshark do, where we purchase dedicated IPs and choose the countries. However, it would be nice to include some shared dedicated IPs in the paid plan, with an additional fee option to have your own Proton IP in a country of your choice — Nord and Surfshark offer this.

Double VPN like Surfshark does — you choose both countries, the entry and exit points. It's not meant to eliminate or improve Secure Core, but rather for a customized Double VPN experience.

Rotating IPs — another feature from Surfshark where IPs change but the connection remains the same, without dropping, without changing countries, making tracking even more difficult.

More secure physical servers — if it's physical, it should be secure. Virtual servers are far away, speed drops and latency explodes. Perhaps RAM-based servers could guarantee more security on physical servers.
