It would be nice to see the percentages for each category on the pie chart. There's nothing quite similar to the .tbl file that RepeatMasker produces, and adding the percentages on the chart would be like the top level of .tbl but with this nice graphical spin.

And a line somewhere on the image for the total repeat percentage (i.e., 100 minus Non-Repeat pct) would be nice to have. I'm not sure where the intended place to find that number is without a little arithmetic.

Here's how it would look before the description.

 4.48% DNA
15.02% LINE
 5.46% LTR
 3.52% Other (Simple Repeat, Microsatellite, RNA)
 0.67% Penelope
 0.01% Rolling Circle
 1.57% SINE
28.65% Unclassified
40.62% Non-Repeat

I think the R script that makes the chart also makes the highLevelCount.txt file, so it should have the percentages.
Here's what gets the above with an external script:

awk -v FS="\t" '
   NR > 1 { p = 100 * $4; tot += p;  printf("%5.2f%% %s\n", p, $1) }
   END { printf("%5.2f%% Non-Repeat\n", 100-tot) }
' *.highLevelCount.txt
