I do see an advantage to tie it to a time period for the customer. If it was just tied to a major version then Unraid would have to make a decision about if a feature belongs in version 8 or version 9. Essentially locking that feature behind a paid upgrade. By making the upgrade tied to a time period they have no incentive to hold features back for the next major version.

I’ve been running TrueNAS core for years. I used to have my applications in Jails on TrueNAS. If you just want to start out learning I think using SCALE and keeping your apps within TrueNAS is a good way to go.

I believe SCALE uses docker for its apps so that should make it easy to migrate your data in the future if you pick another platform.

I think they are using this: https://github.com/microsoft/terminal

It’s what I use on my Windows machines as well. It’s a huge improvement from the old CMD window.
