Feature Suggestion: Right-click context menu/Keyboard shortcuts to rename tracks

[Tobio89]

Hi WebMD devs,

I wondered if you thought about adding one or both of these features:

• Right click context menu for renaming tracks
• A keyboard shortcut to trigger renaming tracks

What do you think? If you're okay with it, I might be able to add them myself and you guys can test it out?
