Allow Dev Tools on Waiver and Preference Windows

[araujoarthur0]

Describe the current limitation
Dev Tools doesn't open on waiver and preference windows => makes it harder to debug

Describe the proposed feature or enhancement
Using the suggestion presented here https://stackoverflow.com/a/37814569, I was able to trigger the opening of a dev tools on the waiver window. Perhaps we could either

• attach the opening of dev tools to a keyboard shortcut
• or add a menu tab when the app knows it's being opened from a dev environment

What do you think?

I'd be ok with it. We already have a shortcut for it on the main window "Ctrl + Shift + I", we could make it work everywhere

You can close this now

@araujoarthur0 a tip: If you write "Closes #XXX" on your PR text when opening it, the issue is automatically closed when it gets merged :)

[araujoarthur0]

Oh, nice to know!

[araujoarthur0]

Could we update the template with this?

Just did on #264
