text size and font IS a good idea. Though I suspect they want to make a good interface 1st, then worry about being able to adjust the text settings (so their default is awesome). We've seen they will have a fallen interface that is not the same as the men interface. If they don't let you change the color of the interface GalCiv2 style, then I'm sure somebody could find a way to mod it in once they've given us code for any sort of interface choices at all.
Since GalCiv2 had the clock added, I doubt it will escape from elemental for long. One can assume its low priority at this stage though.
As far as screenshots with different resolutions from the screen? I'm not sure if thats a good idea. I mean... 1st off, WHY? If you want another resolution, just open the screenshot in an image editor and change the resolution. I'd rather that then letting DirectX do the resizing for me (I can ensure the maximum quality if I do it, DirectX will refer to whatever settings I have for the video card at the time, which may not be optimized for 2D rendering in Elemental) and 2ndly, is it so hard just to change the resolution of your screen before you go in to make screenshots? Chances are if there was a screenshot resolution setting, it would be in the same place the normal resolution could be adjusted, so its only saving you as much time as it takes to restart. If they changed anything about how the screenshots are taken, I'd want them to add a 'naming' feature to screenshots so I don't have to sort through the laundry list of screenshots everytime I want to find one.
