Thank you for your suggestions!
First of all, I'd like to mention that the itch.io "last updated" metric isn't accurate, since I've moved all the change logs in-game. The last update was actually ~1 month ago.
As posted above, many of the things you've suggested are already planned/done for 4.0. The exception is many of your UI-related suggestions-- I'll be adding some of these to the Trello soon. (By the way, you *can* disable power lasers in graphics settings.)
And, no, random spawnpoints will not be optional. I've seen that many people just set up a giant shielded ring around spawnpoints and camp every wave-- this is something I would like to avoid.
To clear things up a bit: spawnpoints won't be *completely* random: they won't change every wave, and only move major distances if player turrets or other defenses are placed near them.
