I'm not sure what these buttons are expected to to - in detail.
The icon with the frames shows / does nothing, the paragraph-icon shows (only?) nbsp, and for the block-elements I miss some tags like br and li and so on (maybe they are no "blocks" but nevertheless helpful).
"BlueGrifffon" has some interesting feature to display tags.
