Tabbed interface

Open all your Campfire rooms in whatever way works for you. You can have multiple windows, each with multiple tabs that works as you expect. You can reorder tabs, and drag them in between windows. Inactive tabs will show the number of unread messages if turned on in Preferences.

Inline Images

Flint pulls all images, whether from a Campfire upload, an image link, or even many 3rd-party sites (CloudApp, YouTube, Vimeo, Instagram, Dribbble and more) directly into the room. Even links to Vimeo and YouTube videos will show a still from the video so you know what you're getting into before you open it.

Clicking an image will open it in its own window within the app where you can quickly see the full size version without leaving the app. If you want to save an image, just drag it right out of the app.

User's popover


Flint features a visual autocomplete for users in the room. Start typing a user's name and hit tab to see a list of completions, and hit enter to insert. You can also just hit tab for a quick list of all the users in the room.

The same works for emoji. No need to remember all 800 emoji, just start typing : and hit tab to see a list of all the emoji, keep typing to filter the list.


Flint has a number a ways to get notifications about messages from your Campfire rooms without having to keep it front and center all the time. Get Growl notifications, Notification Center notifications (10.8), menu bar icon, dock badges, and sounds for all messages in the room. Or choose just notifications, and only for certain keywords, it's up to you.
