I've found it to be very similar to Meteor Slides, but better. Even the name is in the same context!
I've made a locale for Brazilian portuguese which is located here:
I would appreciate if you merge it in the upstream. ^_^
There are two duplicated lines in the locale file: 93 and 113.
This sentence is not appearing for translation:
"As default, the slides are 540x450 but are responsive. If your slide needs to be larger or a different ratio, add_image_size in your functions.php - name the size: orbit-custom and select it from below. In all cases, the slider will fill stretch to the div that surrounds it."
And so "Add New Slide" and "Slide Categories" from menu.
That's it! Keep the awesome work!
