Dash automatically applies tags to your assets when you upload them. You can choose between fewer, more accurate tags or more, less accurate tags. It is a good idea to set the balance to your preferences before you upload assets in earnest, is it can't be changed retrospectively.

With Dash you can create pre-defined download sizes and crops, which are available to all of your users when they download an asset. If you have the need to create maximum dimensions for assets for a particular purpose, or specific crop sizes, now's the time to set that up.

Just head to Admin > Preset sizes to get started.
