The pinebook’s privacy switches (for WiFi/BT, camera, and microphone) operate at the firmware level, the operating system has no control over them

The keyboard operates on firmware independent of the operating system. It detects if one of the F10, F11 or F12 keys is pressed in combination with the Pine key for 3 seconds. Doing so disables power to the appropriate peripheral, thereby disabling it. This has the same effect as cutting off the power to each peripheral with a physical switch. This implementation is very secure, since the firmware that determines whether a peripheral gets power is not part of the Pinebook Pro’s operating system. So the power state value for each peripheral cannot be overridden or accessed from the operating system. The power state setting for each peripheral is stored across reboots inside the keyboard’s firmware flash memory.

A couple of favorites that are different from what others already said:

• I strongly dislike autorotate on my phone so I always keep it off, however it makes perfect sense in apps like YouTube/Twitch. So I have one task that turns it on when opening one of those apps, and off again when closing them
• When I’ve got Bluetooth headphones, I can choose to have incoming texts read out to me. Very nice when walking/running outside and not needing to pull my phone out
• Similarly, I’ve got a task that will (optionally) read out the name of the song that’s playing to Bluetooth

Buzzkill is very nice. I’m in a group chat that gets huge bursts of activity (like a hundred messages) and then goes dormant for a bit, so I set buzzkill to only give me at most 1 notification every 30 minutes, and keep the rest of them silent. That way I can still keep up with it without my phone blowing up

Humans evolved finger nails to separate Lego pieces

…I can’t think of a good reason for toe nails though

Oh I wish

You can even hook up tachiyomi to your home stuff through something like komga as another source

I let syncing run in the background all the time, the app has a ton of settings to configure when it runs so it respects battery/data usage

Android reports the app has used less than 1% of my battery in the last 19 hours
