This plugin is ultra lightweight. It adds a media button above the tinyMCE editor on both the page and post editor, which when pressed copies a shortlink to your clipboard.
The idea behind this plugin is to add short-linking capabilities, without all the bloated code found in other plugins. This plugin does not alter the database, nor is any data saved or collected. It uses the built in WordPresspost/page ID’s in the URL.
