As Rk suggested we need to be working on the options panels and the other pop up windows in the geoscape. Once that's done we can move onto baseview and battlescape.
New pic time with most of the suggestions RK gave in the other thread. I like the way the volume controls have turned out, speaking of which the interaction on the volume controls I envision will be a case of grabbing the slider with the mouse and moving to the desired location. Same with the others.
I think that load and save will bring up another panel similar in size to the one I've shown. That'll have similar saving and loading functions to the original. Maybe linking those screens to maybe F5 and F6 for loading and saving respectively as a quick option to them would be good?
For the texture detail and model detail numbers, I thought to increase the detail click the button the amount of times required.
The one thing I haven't included on this pic is a return to geoscape button or cancel button. I'd not forgotten, just didn't put it in this time
