I thought most people would only need to differentiate different categories of notes (colours), and important ones (blinking), but I guess blinking might be a bit annoying for some.

I thought echoti would be more portable, obviously I was wrong, but couldn't find any echoti command to turn off blinking.

Seems I overlooked a few things when I hacked that up a few days ago.
It did cross my mind to use getopts, but I thought it would be better to keep
the code short, and not make too many changes.
The patched sticky-note works for my purposes, but if I get some time at some
point in the future (can't say when) I will have another look at it, unless you beat me to it..
