Looking for more places to put things has been one thing on many RapidWeaver users wish list, and so too has columns... lots and lots of columns.
That's why we made our column snippets. We started with 2 columns, then 3, then 4... But there was no escaping the code one would need to work with.
So we made some javascript that cleaned up the process. You only need expose yourself to 5 lines of code to get up to 5 beautifully formatted columns.
