Chargie [1] allows this for USB-A. It could be controlled via an Android app.
My problem with repurposing an old Android device is the security issues. Firmware doesn't get updated anymore. An alternative OS like LineageOS or PostmarketOS takes care of most of the software issues, but not the firmware itself.
Another issue is that the battery is going to be years old, and on 'recent old' Android devices its much more difficult to remove the battery.
It does. As you said they are small and maybe you don't notice, but for some of us, it may mess up our muscle memory. I believe parent poster's honesty because in every update, trying to change back new UI elements is really annoying. Worse, some of them cannot be reverted. You have to adjust yourself to a libre software's changes.
Try the defaults until you get the basics. Look at the help file what you can do and what you need. After that you may want to implement seamless navigation between tmux panes and vim splits[0]. It really isn't a must but hey, it is very convenient for starters since they don't have any muscle memory for switching different splits.
After that maybe try to do same with AwesomeWM and that would be the ultimate navigation setup.
This feels like free to play but pay to win kind of games, or cheap base game to release to poison, countless expensive DLCs. But instead of money, it is freedom.
Just because of this I prefer open source projects from smaller developers that are built with labor of love, instead of from big corporate businesses that will eventually try to use you for any kind of profit.
Since topic is similar, I would like to recommend onivim 2 [0] for who prefer vi bindings. It is almost out of alpha and in pretty usable stage. Currently they are integrating open-vsx. Project is open source with dual license and it is currently very cheap for who wants to support, or free to build from source to try.
It's the same strategy that Google follows for Android. The secret juice of the Android app ecosystem is in the Google Play services... And that's entirely proprietary. So even though the OS is open source, it's impossible to truly build an alternative ecosystem. I agree with the author that the marketing rings falsey.
Very cool idea, since this is a niche product why not adding a small qr code for the articles? By this way this could totally be printable. You read articles from paper while commuting etc. Mark the ones you find interesting. At the end of the day you could visit them via you phone if you really want to see them live.
