I don't like the way the tech tree is set up. It's too easy to click around in it and accidentally change your research project, because the last project highlighted is the one that gets researched and any time you switch branches of the tech tree you select the top item in the currently selected branch.

It'd be nice if the bonuses from e.g. Mountainous showed up somehow on the planet tiles without me having to inspect each tile individually. I have no interest in clicking through 10 or 15 tiles to see which ones give me the +X levels to improvement type Y bonuses (which also don't appear to affect anything - what exactly is this supposed to do for me, anyways?).

Several of the places where the improvement type being granted bonus levels are named is inconsistent - the ones that I've specifically noticed are 'population' and 'farming', as well as 'culture' and 'influence'. Please make the naming consistent; it's much easier to understand +X levels to Influence Improvements than having both +X levels to Culture and +X levels to Influence Improvements do the same thing when none of your improvements are listed as 'cultural'. Also, what do the bonus levels do? They don't change the listed stats for the structure, aside from the little number in the upper-right corner of the tool-tip that I assume is the improvement level, nor does it seem to have an impact on the actual planetary production, at least not that I've noticed.

One of the special tile items - I think the 'Ancient Wonder' - lists a couple of improvements to stuff on its tile and then another +2 to cultural improvements built next to it. However, this +2 level bonus is also applied to research improvements. Is this intended and not listed, or is there something wrong with the adjacency bonus for this?

Are there any 'approval' improvements? I noticed that there are tiles that give bonuses to approval improvements, but I haven't yet noticed any improvements that gain the bonus. I also haven't seen any approval rating anywhere in the game, and was under the impression that it and tax rates had gone the way of the dodo.

Even when the main map grid is on, it can be difficult to see against the background image, particularly over nebulae. This is bad - if I turn the grid on, I want to be able to see it.

Suggestions:

Give me an 'end turn' button separate from the 'show next idle thing' button. I don't always want to go through every planet/ship/whatever else I have that's idle, and I also don't necessarily want to set them into guard/sentry/auto-whatever mode. Don't force me to click through all of them to pass their turns or whatever else I'd do with them.

Give me a notification when ships, especially constructors and colonizers, are completed. Right now, I can only tell when that happens by keeping an eye on the planet listing to see when the queue changes, because things aren't automatically launched and there isn't a 'newly completed ship' indication anywhere.

That annoying 'end turn' beep should be something that I can turn off easily in the game options. Right now I'm either not seeing it or it isn't there, and the other sound effects haven't annoyed me to the point of wanting to be rid of them.

Auto-end turn should default to 'off'. I know it doesn't work right now, but the game should not default to assuming it knows when I'm done with my turn and I don't want to have to check it in the future to make certain that I turned it off after the last patch or something like that.

If it's not too much effort, I want to be able to rearrange the GUI. I'd rather have the minimap in the lower-right corner than the upper-right, because the lower-right is where I'm accustomed to find it most games other than flight simulators. I would also like to be able to resize individual pieces of the GUI rather than only having a sliding scale that affects all of them, because there are some parts that are more important to me, and other people might have a different set of preferences.

I'd like to have a list somewhere of colonizable planets, and a button associated with it that lets me assign a currently-existent colony ship to settle there as well as a button that allows me to assign a planet to queue up a colony ship that will automatically launch and and set course for that planet.

I think that's it for now.
