I'd like to suggest a few improvements to the Swatches panel:
Ability to convert swatches from and to normal/global/spot. For example, convert a normal swatch to global, or convert a spot to normal, and so on.
Fills should automatically rename when colour is edited. For example, a fill named C:0 M:0 Y:0 K:10 should change to C:0 M:0 Y:0 K:50 if I do edit the colour to be a 50% black.
Ability to group swatches into folders.
Global colours names should be their values (for example C:0 M:0 Y:0 K:0) rather than "Global Colour %n"
A command to select/delete all unused swatches.
Perhaps create a document palette by default for any new document?
A "Merge Swatches" command that works like in Illustrator
Select multiple swatches at once to delete/copy them
Global, overprint and spot colour indicators should be larger, they're hard to see when the swatch is selected (see attached)
All these are to help us manage & identify the colours, plus correcting mistakes all designers make eventually. :P
Thanks!
