Probably a silly question: I'd like to thicken the borders between panels. The image below shows an example of what I'm talking about, I'm probably not using the right term; here, it's the intersection of the four borders around four different panels, very thin lines. Is it possible to thicken these borders just slightly, maybe a pixel or two thicker? I tried messing around with making an xmlc file edit thingy but I can't figure out the right config to edit and I'm a bit lost lol. Thanks in advance for the help!
