Posts probably represent the most common content on your web. You can easily set up some special features for each your post separately. There is especially a useful possibility to make and manage all the detailed settings via your own presets (see also the generalTheme Options > Single Post > Single Post Preset option and compare it with this Single Preset, which is applied just to the selected page).
After you create a new post (Posts > Add New), you can see the mentioned options placed below the main content field. Obviously, there are the same settings available when you edit the posts you have already created.
