[Elaine Meng]

initial description said "infinitely small" but now I'm not sure whether it was infinitely small or just too big somehow. I accidentally changed size because I was trying to make zooming go faster... it is glacially slow trying to do it with 2-finger scrolling on the trackpad.

[Zach Pearson]

This has actually been fixed since yesterday's daily build! Unless that one had the 2023-04-27 version string too, in which case I need to go look again.

Might also be a good enhancement ticket to figure out the size of the voxels and not let the cursor get smaller than _that_.
