When annotating the heatmap with gene_names, features without a gene name are left blank. While users may fill in the blanks by generating the same heatmap annotated with gene_ids, it would be friendlier to do the job for them.
Implemented.
Bonus feature: the bottom and right margins of the heatmap plot now can be resized to accomodate large gene and sample labels, respectively.
