Improve convenience in setting of auto-grid less than 3 images

For some sites, automatic grids are useful, but only when users upload a larger batch of images. For example, an admin might want auto-grid to start at 5, 6, 10, or another value, rather than triggering as soon as 3 images are uploaded.

This would be especially useful for communities where users often upload a small number of images inline with explanatory text, but larger galleries should still be compacted into a grid.

Can you share a bit more about your experience in particular?

What is the setting you would use and why?
