v4.2.0
Shortcuts configuration support!
Many people have asked for support for changing the "shift + A" shortcut for opening/closing the dev tools to be configurable and I buckled under the sheer pressure and added it to the settings tab.
JSX support
The dev tools would not show up if your root file was written in JSX.
This has been fixed now and you should be able to see the client side of dev tools when using jsx (even though you shouldn't cough cough)
