This window really should show the exact total (or at least another decimal place or two) to be completely useful to the player. Increments of 100k are too wide for this at higher levels.
I had to manually total up the kingdom population amounts to determine how close I was to unlocking the next level today when it showed 1.9 million. Turns out I was only a few thousand from 2 million and just needed to level up one lower kingdom to reach it, but I couldn’t tell without doing the math myself. This window would be much more helpful with more precision shown here.
