The planets' economy system is nearly done. Planet List screen is almost done as well. The only remaining features is to implement infusing a planet with reserves to boost its production, and the dialog for it.
After those are done, I will re-do the Fleet Design List window and implement Fleet List screen. As well as bugfixes and minor tweaks. At that point, I will upload a new version to Desura.
Here's a screenshot of my progress, note the new taskbar at bottom.
