The lid sensor is just a simple switch, it doesn't translate to any key by hardware (though by software, anything is possible).
At the moment it doesn't do anything so yes, it can be configured in any way you like.
Bei mir grad aktuell: Mit meiner Frau zusammen Tales of Zestiria (zum 2. Mal, da wir gerade Berseria durch haben und die ja viel miteiander zu tun haben).
Allein ist gerade "Rise of the Tomb Raider" dran. Hätte nicht gedacht, dass die Tom Raider Serie soviel Spaß machen kann :)
I know... that's an issue with Webmin / VirtualMin (which I use for administration).
It handles MailMan and uses the domain names - but it's own port. And the certificate from that port is from rhea.dragonbox.de
No real idea how to fix that.
Well, battery monitor / charging is mostly done by ToastBucket (but not yet implemented in our test image), speakers being overdriven seems to be a non-issue, as they overdrive if you raise the ALSA volume to 75% or higher - and according to the docs I found, 75% is 0dB, so anything above CAN...
The font size is the same as on the old boards - and the colors are mostly the same as well.
I tried to adapt the theme as good as possible.
But you can also change your theme - maybe DragonBox Pyra Simple is better suited?
I can also create one with bigger fonts.
