Text editing options

[Cabintom]

One last one: Would it be possible to improve the text editing options?
I'm surprised there's no ability to strikethrough (which is useful when editing old posts to show what was corrected).
Also, the ability to superscript is lacking.

Strike through :
now available !
Just use the "s" tags

Superscript :
^{now available !}
Use the "sup" tags
