An attentive customer recently informed me that they were not able to select GIFs directly within Ghost – something that used to be possible on their previous Ghost hoster.
After a quick research, it turned out that a simple configuration option on Magic Pages was missing. This has now been added, so you can select GIFs directly within Ghost's editor by typing /GIF in a new line.
(though, admittetly, you'll just see the result of me typing /GIF)
