I see you're back after the 7 day ban and still spamming about Opengl, but at least you're more polite about it. Please do not double post, use the edit function. Everyone is very welcome to suggest anything, but you will get Opengl when you get it, there is no need to keep repeating yourself. Believe it or not you're not the fist person to suggest it. It is on the list of things to do I would imagine, try to enjoy fpse as it is for now.
I agree with your 2nd point, it is difficult to fully resize the screen after playing with it. I ended up just restoring the default setting, and that seemed to do the trick. But then again if you change the screen size, then save as default, you'lll have a much harder time.
Also, the resizing of different elements is something I think Schtruck will be working on anyway.
