The Magic Delay and Magic Speed select boxes in the Bannerify header allow you to automatically apply timings to all of your layers, across all of your banners with one click.
Magic Delays
If you want all of your layers in all of your banners to have a staggered delay offset, you can click on the Magic Delay select box in the Bannerify header; selecting a delay (from 0.1 seconds to 0.5 seconds) will automatically apply that staggered delay to every layer's timeline in Bannerify for each banner.
Magic Speeds
If you want all of your layers in all of your banners to be the same speed, you can click on the Magic Speed select box in the Bannerify header; selecting a speed (from 0.1 seconds to 1 second) will automatically apply that speed to every layer's timeline in Bannerify for each banner.
