Enable debugging in ACP

[fadedturbulence]

Is there any way to turn on some sort of 'show errors' option for the ACP? For when apps crash/don't work, and throw this useless error:

EX2: Something went wrong. Please try again.

Or a similar error will show. This does nothing for anyone, can't help the dev out with any helpful info and we ourselves can't trace back if we did the breaking. 

Please tell me there is a way to see more info than these more than useless errors tell us.

Thanks
