Ability to open any PHP file in browser

If I want to create a plain PHP file - ie without using App Connect, eg to call as an API from server connect - it would be very useful if it could be opened from within Wappler. I hit F12 expecting the browser to open and of course nothing happens. Is there a particular reason for this? I wonder if it’s prevented as being not necessary - but it would be useful.

Hardly a big issue, but it just seems unnecessary work to open a browser and enter a file name, instead of simply making a keystroke.
