well few days ago I uploaded on the ObjectDock_Backgrounds library my first "dock based" solution to have small/thin separators in place of the normal large size (the OD 2 default)
thanks to the Natas2, DaveBax and skyzyk feedback also Separator II was out, more functional but I see that the separators image embedded in the dockbackground is not very "sharp"
especially when you have many icons and the dock became very large !
Any way here I am with my "icon based" solution : the separator is embedded in 1 icon, you can have \ I can provide different icons to use as separator, right side \ left side, you can use different separators design on the same dock !
The chosen Icon image is modified (moved to one side and resized to create the space for the separator ) but naturally you can still use the icon as shortcut !
a sub idea is an icon with 2 text lines 1 pointing to the left icon group, the other to the right with the names of the 2 different groups !
for now I have only 2 images trials
please be kind ( for the text solution I'm waiting suggestions for the different groups names Thanks !)
