Small update: I just figured out that my eyes are already tired when sitting in lobby for 2 mins. Idk if it's font size or something else... edit: I can't increase UI to 125%, then it's supper blurry and/or weird. 

A quick tips guide should just focus on basics like constant resource gathering and not leaving units idle. New players struggle more with economy than anything else.

I see no case where this wouldn't be useful in birdseye view by default. Perhaps allow it to be toggled OFF, sure, but I think the only real reason to use birdseye view would be to get a strategic view of things and this would assist in that.

Civilization aura joined the chat  I love the idea. I would make it optional, with a toggle in the settings, so as not to force a feature that could be negative for some players or in certain contexts.

No, it goes like a projectile, with a straight trajectory.
