In Fieldlens, you can give each post a title and description. The title is there to help you summarize the issue - along with any photos, the title will be prominently displayed within the Feed. The description can be used to more fully describe what you're seeing.
Note that a title is required. However, if you add a category and leave the title field blank, the category will become your title. Likewise, if you include pictures or video but no title, the title will autopopulate with See attached media.
On both the mobile and web you can click or tap into the title and description sections to fill them in.
