Now it has lots of options to set colors, etc., but if I remember correctly, it didn't originally let you set squares colors. Now you can pick piece graphics, set square colors, and set border color. I think that mostly addresses the concerns. I can only think of two outstanding concerns (one is probably very easy to address, the other is probably not.)
Well, the options to color the squares and use arbitrary sets of piece images has been there from the very beginning. What is a relatively recent addition is that you can also enable a rim with coordinates around the board, and specify the color and letter color of that.
About the coordinates: there already is an option 'firstRank' which you can use to specify how ranks are counted. (And then enables the display of the coordinate rim.) I don't have something like that for the files, as I couldn't imagine this would ever be needed. Bfore 1 comes 0, and indeed some variants count 0-9. But what comes before 'a'? Anyway, it should be easy to implement an option 'fileLabels' that would override normal labeling.
I did not quite understand the other request. You are referring to the 'satellite' that can be embedded in the text to display the pieces as clickable items in an 'unnumbered list'? Would the FEN have to appear as the last item in that list? The list would only be added if you embed the HTML <ul> directive with the proper satellite id in your text. I could easily make it such that items you already specified in that list remain at the bottom of it after the Diagram scripped has filled the table with the piece items. If you want the FEN to appear below the table, you could write it there yourself in the HTML. Or do you expect the Diagram script to generate the FEN? Not all sets of piece IDs would allow a position to be encoded as FEN, though. (There could be multi-letter IDs, of some pieces might have the same ID.)
P.S. There is something very strange with the title of your posting, which is not equal to the title of the subject thread.
