wow I like there is finally on topic discussion for one of my scripts. but for something that started as a three line script things are getting complex fast. for the argument of long lines, that shouldn't be a problem for multiple reasons. the window is a listbox so lines don't wrap so you can only see the part of the line that fits in the window and this is a notes script and the point of a note is a short message to remember something.
also personally i feel an ini would just be easier than trying to create some structure to manage different notes when inis have sections and such.
