I love the ability to use custom icons in DEVONthink for macOS. Especially great is the fact that those icons sync to Devon to Go.
Unfortunately, when I want to use a custom icon for a file, then there’s a little thin black frame border around the icon – but only when viewed in list view. See screenshots attached. All is fine with groups, just not with files. Strangely, the default icons for text items, for example, all the while not being square, they do not have any square border line around them.
Can this be avoided?
