Hi,
in layout add-ons, why didn't you give the option to create a layout with 4 or 6 columns?
The only way to add other columns is to clone the existing column, is this the procedure to follow (but this has the consequence of displaying the initial denomination)?
Also, it's quite frustrating to have IDs on every new element...why not just add an extra class?
A short screencast will better illustrate my point: http://u.pc.cd/2V07
