Just in case you were unaware, there is a text threshold setting that adjusts at which point the text appears/disappears based on zoom level.
I agree that it would be helpful to adjust graph view font size. Sometimes there are certain regions or filtering of the graph where my note titles are much shorter and it would just be easier on the eyes to just crank up the font size temporarily knowing that while it may cause heavy overlap in some areas, I am not dealing with those areas at the moment.
Good idea. Thanks.
