I have a custom script, which changes the fan profile (in my case between two thinkfan config files) depending whether the dock is connected or not. That one gets triggered whenever it switches the power source (AC or BAT0). (AC gets plugged in -> script starts -> check if dock is connected -> if connected run different profile)
It's janky but very helpful when it works :D
I also left my plan, even refunded the amount, since my renewal was set on January 1st.
Main reason I used Proton was their VPN, especially their wide range of servers and countries helped me. But now I don't need that many individual country servers anymore, so I settled to Mullvad, mainly because their prices are very competitive and they are considered "trusted" (even though I kinda miss port forwarding, I'd rather not have it, than trust in AirVPN or other smaller services).
I used their mail for a little while, so migration was rather simple. I currently test out Posteo, when I am happy with them, I might stick to them.
Same with Drive, I didn't use them, mainly because they do not have proper Linux support (no, rclone isn't sufficient).
Thankfully I didn't use them as my password manager (and definitely not as a crypto wallet service) :D
