Presenting Columnizer 2.0
A more dynamic and actually much simpler columnizer based on tables, no hidden buttons or sophisticated actions. You supply a full text, add/remove as many rows to the Columns table as you want columns for your text, optionally adjust fine distribution of text between columns, and the doc does the rest.
Plus, you get an added benefit of using tables for columns: you can adjust their width by dragging, and the content is always top-aligned.
Open in new maximized tab to experience the magic in full.
