Just wanted to chime in w/Ken re sidebar width.
Otherwise I'm still kinda confused, but that's par.
Good work ! 
However... now that the sidebar placement options have been added, even though I have not changed a thing, the sidebar on the right is about half the width it used to be, so article titles take up 3-4 lines where they used to take up 1, maybe 2.
Can we adjust the width of the sidebar column? If that capability is available, and I've missed it, sorry.
Good point. I’ll increase the size of the sidebar if only one is used. It squishes the middle column if both sidebars are as wide as they used to be. Hm. Might even make it user configurable.
