Adjustable scale

I recently spent time creating a map for my campaign. I created the map from an image and added doors, walls, critter and masks. After all of that I realized that each square on the original map was 10' rather than 5'. It would be a big time saver to be able to change the dpi on the fly. In my example, I imported the image at 70 dpi. I would have liked to be able to change it to 35 and have the software just change to grid for me.

Not critical, but it would be really cool.

 

Yup, thanks again. It was suggested that I post this here before you guys came to my rescue on Discord.
