Searching colour problem. I try to search in all my lists (enter, enter) green colour items (colour :6). In result I get not only green items but some items in other colour or without colour. ;-( The same problem occur with red (colour: 4) but not in blue (colour:5) ;) ???

;) I want to sort items alphabetically ("ss") , but CHECKVIST make it impossible because takes into account the color of items..  Can this be changed?
