Extending Panels default layouts I'm making my first steps into Panels (yeah, shame on me I waited so long)... I immediately ran into a problem with the column-resize widget which did not want to obey. So I thought maybe there i a programmatic workaround for my need.

What I need is a 5-row layout:

1: 1 column
2: 3 equal columns
3: 1 column
4: 2 columns (2:1 ratio)
5: 1 column


How do I add a custom layout (with own icon, name and php template) so that Panels recognizes it?
Never mind. Here I found the answer
