Some of these features haven been "touched" previously. The shipyard for example might not need an icon. I believe an underline is sufficient and would'nt clutter as much as icons would, especially considering there will be flags as well.
I forgot about the underline idea, that could very well be all that's needed. My previous post edited.
You've previously mentioned that you're running out of space easily at the smallest zoom levels. I'm wondering, if it is necessary to display stars at those levels at all. At least for systems with a colony, filling the holes in those rings might be an alternative. We would gain some more space and therefor could maybe display more than one quality(different populations/races/outputs etc).
As an alternate display i think it could be profitable to cover up the star with a graph (like this for instance
), but by default i think we need to see the star, otherwise it becomes rather hard to tell which star is which, since at those levels we don't have the star name labels. In other words if you are at close zooms and then you zoom out and quickly loose the names and the star colors, there won't be much to help you keep your place. IMHO the stars become too anonymous.
EDIT: On second thought, maybe we can put this to partial use...
If, for instance, Zoom levels 1 and 2 are smaller than anyone ever need use, i.e. if the largest galaxy at those zoom levels can comfortable fit all at once in our minimum screen size(1024x768), then we shouldn't be inconveniencing the player, if we further simplify zoom L1 and L2. If he wanted that info he can stay at a closer zoom.Can someone measure the pixel dimensions of a maximum sized galaxy at zooms 1-4?
The actual edges of the galaxy should be much more obvious when you select the "Irregular" or "cluster" galaxy shape. I forget which one, but the galaxy looks like a big square, and is thus easy to measure.
