Kate - Source code section for lines range on the scrollbar

[disquisitiones]

Hi Christoph,

thanks for your feedback, good to know that these features can be also of
interest for the project.

I can start to dig in and see what is possible, I will open three different
threads in the mailing list for the points I've mentioned
probably starting with the easiest one, point 2). My idea there is not
really related with the interaction with errors and warnings
(which would be point 3) rather with the possibility of observing the
possible generated standard output while coding but trying to minimize
as much as possible the interruption of the flow allowing for a smooth
cycle of coding => compiling => standard output check => coding without
ever the need of leaving the keyboard.

Thanks and kind regards,

Luca
