Title fairly self explanatory but even so thought I'd explain. On the notifications tab when a trade deal between myself and another race expires, I go into the diplomacy screen to check my treaties, only the trade deal that I've just been notified of has now disappeared, as it should.
The trouble now though is I have no idea what I'd previously traded with for this particular faction. Was it just resources for tech? An economic treaty for open borders. Whilst I can go into the trade screen and normally figure it out, this gets harder as more and more deals get struck with various races.
Is there any way of adding an 'expired treaties' tab in the diplomacy menu, which shows you what trade deals have expired that turn? This means I can view what I was previously trading and re-negotiate any deals I want to continue with, or even see if the race I want to trade with is offering me a better / worse deal after last time.
