Hello,
after install EmEditor v21.4 beta 4 (21.3.904) the place where the buttons were before, is free now. I searched in the “Tools – Customize Toolbars…” the Sort toolbar unsuccessful. By “Special Toolbars” I see “CSV”. In context menu of toolbar’s I see the point “CSV/Sort” I can’t see a single “Sort” toolbar. When I choose this point “CSV/Sort” it show me the CSV toolbar with free space (sort buttons was before).
