We’re sure we are not the only one, that when we save our code on firm level, we immediately go to a company file to see the output of our code, and see a syntax error. For example:
Okay, above can qualify as a rookie mistake but you get the idea: we lose time by saving our code and going back and forth between firm and company level to check when the code is verified.
However 
Now there’s a new function in the ribbon! You probably noticed the small bug icon here:
This is actually a verify function, in which you can verify your code before saving it.
If there’s an error, you’ll see where the issue is and why (when hovering over the red cross button):
Hope this makes up for some time when coding!
PS you can use a shortcut as well: CMD+ENTER (macOS) or ALT+ENTER (WINDOWS)
