But this is a free extension, and maybe for that reason, it hasn't received all the attention it should from the programmers.
The settings panel is lacking. Why not give the option for vertical (rows) or horizontal (columns) or even both.
You must use all three panels. ...why? Why not 2 panels, or 5 panels, or (again) two rows of three panels.
This module is gorgeous, but only works for people who have exactly three categories they want items pulled from, and who want to display exactly three items in a row.
After close to two years, I can only hope they re-evaluate this extension, and decide it's worth some new features.
