ability to resize the note size (so can fit in an increased number of notes on one desktop);
ability to have multiple pages on each note which you cycle through like in yellow notes applet so that you can have more than one note on the desktop but only take the space of one;
ability to bold text so that the bolded text can function as a heading for the note;
ability to change font and text size and color.
Perfection would be the ability to 'scribble' notes
Clicking on a note should raise it above the other overlapping notes.
it would also be nice to be able to move a note without putting the desktop in edit mode.
hide all and raise all functionality. hide all should leave a small button. maybe in the toolbar? like in similar apps on linux and windows.
Nice app indeed. I'm using Yellow Notes and like his feature to have multiple notes within one window. Maybe you can add this as an option to Sticky Notes?
