Just a few examples I use on my S23:

• Hiding the alarm and VPN icons from the status bar
• Charging the battery to only 85%
• Rearranging/deleting the camera mode favorite buttons (Photo, Night Mode, Video, ...)
• Creating folders in the app drawer of the default launcher
• Option to customize the long press of the power button (I set mine to the flashlight)

Don't invest in crypto.

No, because a cow has to be impregnated and their baby is taken away (and either killed (male) or is also going to be a milk cow (female)) just for you having some pleasure.

Yep, Kagi

Kagi is also really nice. But it's not free..

Not trusting in science.

Edit: Since there are many comments, I would like to clarify my statement. I meant that you should rather trust scientists, that the earth is round / that there is a human-made climate change, etc. and not listen to some random internet guy, that claims these things are false although he has made no scientific tests or he has no scientific background. I know that there are paradigm shifts in science and sometimes old ideas are proven to be wrong. But those shifts happen through other scientific experiments/thoughts. As long as > 99 % of all scientists think that something is true, you should rather trust them then any conspiracy theorist...
