Queue for Hero Skills

A typical long game of Endless Space 2 will involve 4-8 heroes levelling up to 20ish. 

When you do the math, this ends up with a player opening the notification, clicking inspect, and choosing a level for the hero, up to 160 times. That means you're stopping to pick a new skill almost every turn, interupting the flow of "strategy" you've got going on. 

We have a research queue because constantly picking new research is tedious. We have a construction queue because constantly picking new buildings is tedious.  

Why not have a skill queue for heroes? You pick the skills you want them to unlock in order, and they do so next time they level. 

4X games are well known for being too "micromanagey and slow" in their end game. The repeated selection of hero skills adds to that tendency.

Fixing this would be intuitive, retain player control (they're still picking their skills), and give players more time to focus on meaningful decisions and actual gameplay.
