I would like to insert columns for extra light cue's, video or audiotracks. It seems now that I have to shift everything to the right for making space. In this case I loose transition time and more. Is there a possibility to do this??
Be sure to edit the board (CMD+E), then click the "gear" icon on the column : a popup will appear, and you have "<" and ">" button to insert a new column (or extend if you maintain ALT, see message on "i" icon).
You can also, drag-and-reorder a column.
