How can we permanently enable battery saving mode (automatically)?

Yes even when plugged in.
I hate javascript eating my CPU.

Re: Allow to always use battery saving

@leocg works great even with 1080p, I recommend enabling this by default (at least for ssds).

When watching a simple 720p 30-50min youtube clip why does Opera write 2GB of data to SSD?

It slowly reduces it's lifespan.
Why do we have 4GB+ RAM if we still write to SSD?
How to turn this caching off?

Some weeks ago CTRL+SHIFT+T stopped working correctly, it used to open last closed tab in current window, but now it opens Random old tab on a new window.

I couldn't find it under Shortcuts, so it has to be built in function.

This is such a basic feature that worked for >10years, why is it broken?

Also history is not correct, this might be the root cause.
Clearing history doesn't help.

Works perfectly in Chrome.

Tested on 76.0.4017.123

Swyware! thanks opera!

Typing "http://nx.bit/" gives: ERR_PROXY_CONNECTION_FAILED

Also 7 days of caching is very bad for dynamic DNS, where IP can change daily. (typical home ISP)
