I understand that the boxes in Graph View are supposed automatically to fit the text
width. But in my case it seems not to work very well. I suspect it it would be a more economical use of space, make it easier to navigate and even give the image an improved aesthetical feel if the boxes really took up only the space needed by the text to be displayed. I use the Graph View a lot and like it very much.
I am using Gramps 5.1.3 with SQLite and graphview 1.0.123. on OpenSuse Linux Leap 15.2,
As you can see from this screen shot the boxes are about double the width needed for the text, although Graph View is configured only to show full dates, but not images or avatars.
