split "advanced" section into different sections

[evanwill]

something like:

• "customizations" (the mini guides to customization, like timelinejs, new cloud, repurpose timeline, etc) -- or is this like "recipes"?
• "template info" (advanced details of the template, like custom css, add analytics, etc)

not sure the correct labels/categories, but "advanced" is getting too big.
What about the sort of conceptual ideas, like "workflow for multiple collections"?

I like customizations. and splitting this out a bit, -- looking at the entries, we could probably create a couple different options.

Also maybe a section on the Add-Ons, CB- repos, etc.

It also opens up the issue of revising the web page overall tho ... and maybe having some pages for the search hub + workflows for multiple collections as that becomes more real.
