[Change default ruler?]

I went back and played with this program again and suddenly I answered my own question! The answer is to go up the the left where the vertical and horizontal measurements lines are and you will see one of the following: px, in, ft, and more. Right click on the letters and a menu will come up with all the different measurement values that anyone wants. Click on the one you need like I did.  Guess I just did not try hard enough to find the answer. I am old and have a short attention span, so pardon me.  Hope this helps the rest of you

[Change default ruler?]

I have read the posts, but have not figured how to change the rulers to show the photos in inches. Apparently it is showing it in pixels, I suppose, as at upper corner of ruler, there is a px.   I am used to working with inches and feet, not mm or pixels. To me is would be one of the basic settings to have on this program. I am disappointed with in 30 minutes of downloading this program. I was using an ancient program Picture Publisher on a PC that was great. Dealing with dpi and the rulers  are in inches, not px. The new windows editions won't run it, but when I used it if I wanted to set a photo to 4 x 6 inches, I simply did that. I ask: Is there a way to do this with this program. If so, please tell me in steps of how to do it or I won't use it or purchase it.  

Thanks for any help
