Yes, I would second this as a great thing to add in any future updates.
Reason being is that I added a title on the page to show the category of the sponsors in a given section (Benefactor, Champion etc) and then inserted the short code to display a grid of the sponsors from that category. Then I have a hard break followed by a horizontal line with name of the next class of sponsors, and then the short code for that category. I have gone about making sure that I photoshop all the logos to be the exact same size so things stay uniform, and have even created a default logo that I use for individuals who have donated to our organization since any sponsors who don’t have a logo get rendered as a simple link (which is fine) but that goes and messes up the grid when it is a mix of logos and links.
For now it seems to be working, and I am getting around a few issues that would be nice to improve on, but as I am building up my sponsor DB, I know I have some that I still need to add where their logo is a little more abstract so it would be nice to have the name of the company appear directly above or below the logo similar to what is in the widget.
