Feature Request: Character Count
Would be awesome to have the chance to have a **character count** into the text panel. It's very helpful when designing for web and keep consistence with the **45to75 principle**. 

Right now I use this simple plugin just to do so: 
**https://github.com/andrewfiorillo/sketch-character-count**

I'm looking for a command that can **count the characters on a selected paragraphs** and/or if text is highlited into a paragraph to **count just the selected line**.

Thanks Ashung!
