Handle favourites, reading lists, spam, friend lists etc. Can be applied to any entity (nodes, users, comments etc.) It appears as a clickable link. Can choose between page reload and AJAX when user toggles it. Linked with views, and you can trigger events when flag count reaches a threshold.
There are situations where you will want to hide a node title - e.g. if you have a view and insert an image field that's an entity reference to another content type. Module allows you to hide titles by content type or view mode and for all nodes or just a custom selection. Beta in D8.
Add Next/previous links to node view for specific content types - e.g. image gallery. Powerful - supports: next/last, random link, you can specify exact text used etc. Currently a dev version in D8.
Setup: activate for a content type in the 'Edit' tab (NOT manage display). Once Flippy is active, Manage Display tab will have a pager field so you can reposition the links relative to other fields on the page (e.g. above or below image).
