HexHelper

Easily convert  between  all sorts of different units with HexHelper, a convenient menu bar utility. 
Ever needed to quickly see the binary representation of a hexadecimal value? Or to know what that decimal value means if interpreted as UTF-8? This and much more becomes a breeze with HexHelper, and you can even copy the result of the conversion straight to your clipboard.

HexHelper is a simple little hobby project I made for myself and found useful enough times that I wanted to put it out there and see if it might provide some value to others too. I gladly take feedback and feature requests, but as a hobby project I have only worked a little on in my spare time, it may not see that rapid development. The code is on GitHub though so feel free to read, modify or contribute to it.
