Change Color Set
Corel like color set is useless for professional use. It's full of trash (colors which user will never need), and there are no info about colors. This must be change!
On starting of application only 4 items in color set are needed:
2. white (0,0,0,0)
3. black (0,0,0,100)
4. registration (100,100,100,100)
During a work, application should add new colors which are used in project into a color set. If user change some color in color set, he also change color for all the objects which are connected to that color. User can't change starting 4 colors.
There is also need for some info for every color. I recommend color name (name given by user or color code) and color tipe (CMYK or spot).
