It would make it way easier to find declaration of war, messages from a specific person etc.

Ctrl+F does the job for searching terms like "war".
As for reading political state of affairs ... you have to keep your notes locally

Ctrl F also doesnt help anymore, since chat now loads in pages of 200 messages at once.

If you're a member, you can call the GameFeed API with &GetChat=true which will allow you to Ctrl F all messages at once.:

Okay, thanks, I'll use it

JK what are the odds you made a gui for it somewhere?

It’ll be member only to use an API solution.
There are other ways to read chat but it’s more complicated and browser-only.

It’ll be better for you to take notes of what happened in the game. Could use Notepad or any other word processor (eg LibreOffice Writer, MS Word, Google Docs) to keep notes.

Dan I was thinking for when I do eventually get a lifetime membership.
