Here I will try to "rate" - on a complete subjective basic - some Plugins for Confluence

RefinedWiki Original Theme

Marketplkace listing: https://marketplace.atlassian.com/plugins/com.refinedwiki.confluence.plugins.theme.original

A fine plugin for spicing up a site or space relatively easy, with several very nice themes right out of the box, combined with a wide color range. A fair part of customizations are available for headers, footers and menus.

The designs are very usable, but I find the Dashboard links, breadcrumbing and links a bit confysing and also the language parts are quite poor. The theme has alternate styling for blog "dsfsdf" wich makes the blog lokking very bloglike, and very little confluence like; wich for my part is not good, as the blog looking is distancing it from the pages looking, as if I was actually using two seperate prodcuts 

The footer designer is pretty nice, but also quite limited, making the footer 90% of what You were aming for. 

I have not tested the Dashboard part. 

Enterprise Theme

Marketplace lising: https://marketplace.atlassian.com/plugins/net.getunik.confluence.skin.core

This is a very usable pluging with a log of extra usable Macros available, even if the Theme is not active on a site, making is usefull with other themes.

The design is rather flexible and the fact that You have a wiki markup "placeholder" for both headers, footer, sidebars and below contant make it easy to set ind extra macros, contents and stuff, that would be relative diffecult to put in otherewise. Also, all the content placeholders can either just inherit from the global design (in the Confluence Admin section) or be maintained per site, very very flexiple.

Also, quite som fair amount of styling is available, though the lack of fontsizes are completely missing, and the font are set rather small for the theme. This can be fixed easily with the following stud in the Global HTML (or style pr. space):

Also, the theming and the sidebars are very flexible for admin to set design, and some very special features as "Set as landing page" versure the default "Embed page View" are very nice and gives users a good inpression on hitting a page (this is customizealbe per page):
