However, Colour0, Colour5 and FontHeight did not change. This is probably because 1Remote's protocol runner setting is further overridden.

https://github.com/1Remote/1Remote/blob/main/Ui/Utils/KiTTY/IKittyConnectable.cs#L46-L102

The session file is loaded first, and then the setting parameters from 1Remote are added to the list. That’s why Colour0, Colour5 and FontHeight did not change.

I think we should change the order, what do you think?

Well. I dont know, It's a little weird that the theme will be overwritten, but I don't think it's a big deal.

BTW, you can't switch the order completely, for example, the hostname in the GUI should not be overwritten by the session file.

Current priorities are:

user's session file (all configurable) < Configuration items provided by 1Remote GUI (e.g. connection info) and some implicit configuration items < Theme

It depends on the mindset, but this makes sense too.
Okay. I withdraw the proposal to change this.

Actually, I don't have any particular insistence on this, except that connection info cannot be overwritten, others is ok either way.

Theme < session file < connection info, is ok to me.

BTW, A same dilemma in RDP：
