My thoughts at present:
Unit: Riot Starship - I think this is a cool one, and something to do for this month's free DLC.
Rebalance: Special unit re-balance (post triangle change) - Balance is always something we look at just as a matter of course, and we'll definitely look at this before long, either way.
Concentric Circles Map - New map types are only for expansions, but I'll keep this in mind for the next one.
Feature: Deathmatch survival gametype - New gametypes of this scope are probably for expansions.
Feature: Engine Burn Effects This is a pretty substantial feature to work in (not from a coding sense, but in terms of lining up all those burns with the various ship hulls), and I suspect it will harm performance for nearly everyone who uses it, so this makes it not a terribly high priority for me personally. But, given that this is fairly popular of a request, I will definitely keep it in mind for the schedule.
Feature: Formation Movement Mode This has been something that I have thought is very cool for quite some time, and from the votes it seems this is the clear winner, too. We've implemented a partial version of this already, and we'll do some more iterations in the coming weeks with expanding this functionality.
Feature: Draggable planets in galaxy view I'm not real sold on this one for a lot of the reasons people cite in the thread about it.
Feature: Mouse Scrolling view This seems like definitely one to do, any it should be pretty quick.
Feature: Configurable Autosaves There probably needs to be more discussion about specifics, because there have been a lot of ideas about this over the months, but I think this is something that deserves some attention.
Feature: Adjustable Resource Cap This is referring to just the spillover of resources to allies, which I hope people realized when they were voting. I think that aspect will be great, and something to look at. If people were mistakenly voting for this thinking it was an adjustment of the overall cap of resources you can amass, that's not something I'm willing to change because of balance reasons; there are cheats for essentially infinite resources for those people who want that. But, assuming that people were voting for what this feature actually is, as per the link posted in the first thread, I'm with them that I think this would be helpful. Though, I wonder if perhaps one of the other suggestions about something like Trading Posts, etc, might be a better way of solving this same problem.
