I'm trying to add custom Display Items to the Fonts and Colors dialog. I can successfully save and retrieve colors using the IVsFontAndColorStorage service but the items do not appear in the list of Display Items. I have tried following this blog post about adding a custom category. My category appeared but only with the default display items. My real goal is to add my custom colors to the "Text Editor" category. ReSharper does a similar thing.
Have anyone had experience with this? Is there a nice tutorial out there?
