Layout Changes

If anyone has any suggestions for changes to the site layout I'm open to hear them.  Visual design isn't really my forte.  Although there are a lot of changes that I may not be able to implement.

I would love to remove the title from comments and forum posts since it's just the first few words of the post but while that's apparently easy in Drupal 7, the only suggestions I've found for Drupal 8 involve editing source files.
