[Kst] Annotation exporting and other feature needs

Hello everyone, I have looked at many other data plotting softwares and 
KST seems to be the best foundation for what I need.  I'm not well 
educated in C++ or any programming but am motivated to learn if I need 
to.  I was wondering if the following might be considered for inclusion 
in future updates or if what I need could be built with a custom plugin.

I analyze 30-40 minute csv streams with hrs:minutes:seconds as the X 
axis and plot 9 to 11 Y axis curves.  I zoom the x axis to one second 
intervals or smaller.  I would like to have the ability to highlight all 
y data points at the same time as I pan through the data with my right 
and left arrow keys, contrasted to being limited to highlighting data on 
just one curve as it is now.  I would also like to be able to annotate 
at particular places on the x axis and be able to export those 
annotations to another csv file for a "bird's eye" view of my 
annotations.

Are my wants going to be difficult for an experienced programmer to 
write, or does it seem fairly do-able?  Are there any professionals out 
there that would be willing to bid such a project? I've looked at the 
source with kdevelop and have not been able to find the "highlight data 
points" mode feature.

Some free programs have limited exporting features but are not really 
good enough to use extensively- such as datplot.  Panning is a real 
chore as it must be done with mouse keys or by dragging the mouse.  
Other programs have good highlighting features but do not import typical 
csv files.  I tried out Sigma-plot and was very disappointed - kst is 
better already for what I need.

Having the ability to plot multiple y curves in the same plot with their 
own Y scale would be very nice as well, my data curves range from a 0-6 
scale on one y and 0-4000 on others, with several 0-100 in between.  
Plotting the Y curves in separate charts is the only way I can see the 
0-6 curve, and that is something I can live with, but it would be great 
to see all curves in the same plot.

Thanks, Jason
