Hey,
a thing that I noticed a while ago and is still a “problem” until today in the download assistant: There is no way to increase the sizes of the sections or the window at all. I just wanted to install something and there is no way to get a nice view over the programs you could install. You have to manually click pixel by pixel with the scrolling arrows.
I was yesterday doing some updating and noticed this. Maybe I am crazy, but I remember that the separations were larger before. It is indeed very annoying if one wants to take a look under all installable programs.
