If I import a pcl file, which typically has two columns of annotation, I have to choose between them in terms of displaying them on a cluster. It would be much more useful if instead of radio buttons on the menu, they were check boxes, so I could display multiple annotations. The gene name is most useful, but not every gene has a name, so I also want to see the ORF name too. When there is no annotation, showing NA is not useful - it would be better if it were blank. In displaying multiple annotations, it would be best if they were aligned in columns, whose widths could be adjusted.
