Modules

Render a table of contents via jQuery plugin.

Specify selectors for content headers, and the element to search within.

Pin items to an image.

Default text plugin, but you can create custom ones for advanced features.

Use entity tokens to map field values to index fields.

I used this module to format a date field as a year to use as the index value.

Configure default entity values from available tokens like the url path or query arg.

[current-page:query:topic]

/node/add/class?topic=12

Ajaxifies an entity form. Combine with Simplify, Entity Prepopulate, and Form Block for some flexible ways to add content.

Edit fields in views.

Create views listings from an API query.

Use GET instead of POST for views ajax filters.

I think this sets the browser urls when you filter the view, so you can click the back button in your browser.
