where is any documentation on the UI ie what all fields, columns, colours mean

[decard123]

as above.

i cannot find any QRG to help explain what everything in the UI MEANS

The UI is quite straightforward. It is heavily inspired by uTorrent. The wiki contains explanations for peer flags, options, and other things: https://github.com/qbittorrent/qBittorrent/wiki.

If it's the BitTorrent protocol terms that confuse you, you can check out these resources to learn about them:

There is no documentation what the meaning of the Flags column in any of the documentation that I have found and many things are lacking in the documentation. Is there a COMPLETE documentation for qbitorrent?

There is no documentation what the meaning of the Flags column

It has a tooltip for that.
