grease pencil - much needed features

color picker - when you are working with lots of colors it gets tedious to constatly search for the right color in the material tab. ( DONE )

groups in the layer tabs. i like the way current layer system is handled but it's missing some very important features like groups. i think it would be wise to extend functionality of the outliner tab to support manipulation with grease pencil

there should be way to switch between layers in the fullscreen mode (could be very easily solved if the layers tab was added into the N context menu in the viewport)

set matte in the adjustments - sometimes your image needs to be drawn or masked over only one layer and the current implementation is not very helpful in that regard (motion graphics rely on this quite heavily for example)

easy way to create new materials, right now it's 4 clicks before you get to pick the color when you make new fill layer without stroke which introduces mayor downtime. ( PROBABLY SOLVED WITH COLOR PICKER )

converting fonts into grease pencil ( DONE )
