Decode/Encode in Hex View
Brought to you by:

In hex mode, it would be helpful when selected bytes are decoded (to short, long, float, etc. numbers).
This could also be extended to other sorts of encodings like cipher-algorithms (DES, AES, Blowfish).
Additionally, the opposite direction would be useful. For instance: Enter a float value in an input mask, which is then encoded. The resulting bytes can be pasted into the document.
