The Edit Form Warn module is a simple module that adds javascript to pages with content forms. If any field has changed, a warning message is shown before the page is left. It adds the javascript that checks into the forms for nodes, media, and custom blocks.
This module uses a jQuery script to provide an animated "back to top" button in the bottom of the screen of your web-page. This is both available on you websiten and the admin pages.
Group context module supports the Group to achieve the context functionality. This module works like og_context(sub-module of og) module. You can create your own context for groups.
