I would love to use this plugin, but running into a little problem. I only want to add about 10 buttons to the editor for my users. Most are in row 3 by default and 2 buttons are in row 4 by default. If I choose to put those 2 buttons into row 3 (so all the buttons I'm adding are in a single row), the editor doesn't load at all. I just get a blank white box where my content should be -- no buttons, no content. Just the WordPress Visual/HTML tabs at the top. If I go back to the settings and add a button to row 4, it loads again, but I'd really love to get them all on 1 row.
