Did you know that if you have a multi-line text box/field in either a Document or Picture Library that your only formatting option is plain text? If you were using the same field in a List, then you get the options of configuring the output as Plain Text, Rich Text or Enhanced rich text.
I didn’t think that was right so I went digging through the object model to see if there was some magic property that I could change to make this happen. Using the trusty SharePoint Manager utility, lo and behold the Rich Text Property!
The only drawback I’ve experienced with this so far is that if you ever update the column in any way, for example changing the name of the column, this property will reset itself back to the default ‘False’.
