Since this is my first post, I wish members of the forum a healthy and prosperous New Year. I want to merge a completed tree I have been working on with an existing one. In RootsMagic 7, I could open both trees side by side on one screen and then move individuals or lineages from one tree to the other. If I try doing the same process in RootsMagic 8: the newly opened file completely covers the existing window! I know I could resize the boxes to make them fit on one screen, but that seems like extra work when this feature worked so well in RootsMagic 7. So what have I missed? ---

I don’t think you have missed anything, this is the RM8 works by opening a new window. As you say just resize the windows. ---

On mac there are inexpensive apps that handle window resizing well: Magnet. ---

Thanks for the suggestion. I’m a Windows guy, so I looked for a Magnet alternative. I found DisplayFusion, which allows me to open 2 tree files, 1 on the right side of the screen and the other on the left side. I downloaded the pro version of the program, which will revert to the free version after 30 days. I’ll keep my fingers crossed that I can use this feature at the end of the trial period. ---

The Windows OS is pretty good at window management by itself and you might just need to google how to show 2 file windows at half size. Windows does 3 things better than Mac: window management, dpi command to increase text size everywhere and no one knows what the 3rd is except perhaps catching malware. ---

If I google what you suggested and find I could have done it through Windows I’m going to feel really stupid.🙂 ---
