Sometimes we forget some of the basics. Had a customer ask if you can maximize the code editor Window in RAD Studio and edit two files side-by-side. I’d heard someone talk about this a while ago, but I couldn’t remember the details.
There is an option in Tools / Options / Editor Options / Display that allows a code window to Zoom to full screen.
With Windows 7 or Windows 8, just drag this new code window to the left or right edge of the screen and it automatically gets tiled nicely.
