[Feature Request] Add battery info widget

[sobakintech]

Is your feature request related to a problem? Please describe. In my area, we constantly have power outages, and my server running CasaOS is a laptop, so when the power is out, it can run for a while, but my server is running an MC server, so I need to check the battery levels through the terminal before it just shuts down and doesnt save the world.

Describe the solution you'd like Add a new widget for battery info, or add the battery level to the already existing widget of system status.

I could use that too. Same situation. Minecraft server running on Crafty on CasaOS and had world corruption whenever power went down. Moved everything onto a laptop. It would be useful to know how much battery the laptop has left without having to physically go to it and look at the screen.
