My first attempt with the concrete5 editor....I found that when creating blocks of text using the "code" style, carriage returns were lost during the save process and the text would display as just word-wrapped. Discovered that doing shift-enter resulted in the desired new line being created.
Problem is that, even after saving the block the way I want it, if I reopen the block for editing, all the newline characters are being lost. This seems buggy to me!
