Hi!
Today icon fonts are a de-facto in UI design and there are tons of libraries available.
It would be very useful to have a glyph palette or studio to list them all for quick&dirty usage in projects.
Just a simple grid should work.
Pick or double click to insert them in a text object.
I know you love to do things "the very Serif way" so candies such as CSS escape code or hex code label for each character should be a well praised feature! :)
Cheers!
