Is there a configuration setting that changes the html editor's html generation so that it uses <br> tags instead of <p> tags for new lines? I guess this is a tinyMCE related problem and it might not be addressable here. I find it a little annoying that pressing enter spreads things out so much. I have been using plain text as my default because of that.
Other than that one issue, I very much enjoy using roundcube, and I want to take the moment to thank all the developers for contributing.
Thanks, Marcus Wu
