Summary screen every 20 years

[Samwise38]

I find it difficult to monitor my empire's growth in the game, particularly when compared to games like EU4, which provide more comprehensive graphs. Sometimes, I lose track of my accomplishments during gameplay. To address this issue, I believe it would be nice to introduce a summary screen that appears every 20 years, highlighting my progress. The screen could include the following information:

• Colonies: 20 years ago versus present
• Population: 20 years ago versus present
• Systems: 20 years ago versus present
• Fleet size and strength: 20 years ago versus present
• Resource output: 20 years ago versus present
• Victory rankings: 20 years ago versus present

Additionally, I think it would be helpful to have access to all past summary screens. For example, after 100 years, I could view five distinct summary screens. These screens should be readily available within the empire tab.
