Sniplets is a generic text insertion plugin. Use it to manually or automatically insert data, PHP, syntax highlight, and almost anything else!
this plugin stops the 'add media' button in edit post from working
I appreciate that this plugin is not tested with 3.4.1, so I will log the issue here without marking the rating down.
When this plugin is installed to 3.4.1, it causes problems on the "Edit Post" page where the Edit Status and Edit Visibility links and the "Most Used" Category tab no longer work.
Although I installed the plugin some time ago, because it looked useful, I've not really had a chance to use it, so will not comment on its effectiveness.
