Now that we only receive notifications (not mails) of activities involving our gatherers, it is very easy for those notifications to "slip off" the report screen when we are say ... sleeping. I would like to request that notifications be maintained for a minimum of 24 hours.
In addition, it would be helpful to break down trade notifications into Gathering and Trade; my search for how many Brascan Seeds are left on a square is complicated by not being able to filter out caravan dispatches for quests and gifts sent to new players, not to mention trade offers posted and accepted and caravans sent between towns.
For active players and/or those with a large number of cities (and I only have 8!), sifting through the notifications is a lot of effort, and I don't see that it necessarily adds value to the game experience.
I know that we can't do everything, but it seems reasonable to give us tools to enable us to be successful at our chosen paths whether we are casual gamers who only want to check in once a day or obsessive gamers who want to manage armies of cotters.
