Is there a way to only show glyphs with red arrows?

Is there a way to create a smart filter that shows glyphs with red arrows?

That could be an addition to the plugin. Something like a entry in the context menu: “show all glyphs with red arrows” (@jkutilek)

The plug-in actually does have such a menu entry already: Edit > Select Glyphs With Outline Errors:

Use it in Font view, and then open a tab (Cmd-T) with the selected glyphs.
