You've done some awesome thing as far as layout options. Mostly done with widgets yet the widgets highlight button/link is gone when we need it most. Will that be brought back for the stable 7 release?
I installed with the full demo content. The Manual collection has three columns, left column(sidebar1) content column, right column(sidebar2). I won't be needing sidebar2 so I deactivated and then deleted all it's widgets but now I have an empty right column. I was kind of hoping everything would self adjust and center itself.
What would I need to do to just have a left sidebar and right main content, centered?
Suggestion/imho opinion - take it or leave it
Demonstrate the three column layout on one of the Blog collections instead of the Manual as I think it would be more apt to to be used on a blog type collection. Left TOC and right main content is pretty well standard for docs/manuals/wikis.
Did run into one install issue. I couldn't log in after install because hash/Salt. Deleted basic_config and went back to install and it recommended converting db to utf8. I did so and was able to log in then. Didn't want to read the hash Salt in non-utf8 encoding I guess?
I figured out the right column thing. Turn off 3 col layout with the "customizer".
