Yes, but left or right glyph. For example, see all the pairs for V with left group a: Va, Vagrave, Vaacute, Vacircumflex, etc.
this would help a lot when making kerning exceptions! Or could there be a script that does such?
Of cours, one could just write a sample text with all the pairs in there. But sometimes I set up groups differently.
Now, if you click a pair, it will add that pair (or one pair that is defined by the classes) to the edit view. If it would add all combinations, it would add a lot of text. But I could add an option to the gear menu.
