I know that habit of using messenger app for notes :) Try [matrix] using Element or SchildiChat. It’s e2eencrypted and federated, and even supports markdown formatting in messages. Also some Slack features are included. The only issue for non-techy person might be verifying sessions - just be sure to use the same client on all devices.

If by wirelessly you mean via Wi-Fi network then one convenient option is qrcp. It generates a QR-code right in your terminal, which you can scan with a phone and send/receive files through a web interface on the URL it provides.

If you want to transfer files regularly, there is another option. Almost every distro has Python installed, and the Python has a “built-in” FTP server. You need to just cd into desired directory and run the command python -m pyftpdlib -w. It will open a FTP server with root in this directory. You then can access it through a file manager, like Material Files for example, and send files and folders back and forth. In Material Files you can save the server address for future use.

I’m glad I didn’t sit by and deleted all my posts and comments.

Wow, this one hell of a monster will take a place of honor among my containers :) Thanks for sharing!

+ for percussionist :)

This + package to enable VSCode marketplace. The only VSCode features it lacks afaik are out of the box settings sync and remote container development, which colud be substituted with plugins.

EDIT: also be sure to check out Lapce suggested by Yote.zip - it’s a banger.
