After updating to WP 3.9 and the latest version of TinyMCE, the table "buttons" are gone from the editor, and replaced with a single table "icon" with dropdown menu options.
This alone is bad enough, because a row of single-click button functions are MUCH more efficient than hierarchical drop down lists! But that's not all... now when you click ANY of the functions - add row, delete colum, anything - the function executes but the page editor view instantly scrolls back to the TOP of the PAGE. This KILLS productivity, especially on long pages where we have to constantly scroll BACK down the page and figure out where we were working.
PLEASE correct this scroll / redraw glitch and post a release asap. Thank you.
(And please put the row of buttons back in your next major release!)
