Paint brush editing.
After using Instant for about a week or so now I absolutely like it a lot for photo filtering however, it would be cool if some capabilities where added.
Like being able to use a paint brush on specific areas of a photo to dial in certain levels of Intensity, Vignette, Emulsion, Grain effect.
