I have version 0.6.3 which seems to be the latest, but in the "Change tag to" menu, there is no entry for a sup option. But with the regex box checked, as you say, it may work. I'll try that tomorrow. thank you so far!

Edit: I had a look on it, but "Change tag to 'sup'" is not possible, as there is no option in the dropdown menu.
