Quality of Life Improvements to implement:
1: Personally i don't mind this, but yes it would be nice to have an in-battle toggle for this
2: If the enemy are retreating, then there is a "claim victory" option or smth, and with regards to the times taken i think you might be exaggerating a bit here, but iirc there is also an improvement for this in the pipe for the next update
3: Better speedup for long distance travel would be nice, but the current default speed is fine for tactical in-system maneuvering
4: Hyperspace isn't perfect, but instant travel times wouldn't fit the style of the game
Game balance improvements
1: "Gives me something to invest in for the end game." The game isn't finished, and we haven't got the actual "end game" implemented yet.
2: "That make the end game so empty and boring." same as i said in response to point 1.
3: "I want more endgame content" a repeat of the above (sensing a pattern)
3(?): Colonies are a secondary focus of the game, they are getting some attention in the coming update, but they are not the main focus of the game.
4: This is intentional, they are 1000 range energy weapons, and ships that can mount energy weapons are balanced around their only long-range options being beams.
5: Level cap is specifically set where it is so you have to make choices in skill picks but can still reach a high power level.
6: "I don't have 80 hours to grind out this game." well this is a long-form game, not some rogue-like where you can run straight through it in an hour.
And in general, using allcaps / "Fix this immediately" gives your post a poor tone, making it less likely that any valid points will be noticed.
