NoteWorthy Composer Forum

Placing a spacer ("Ins" key) before a note will move both the note and its accidental in the same direction.  (It will also move everything else in front of the spacer, however, so some care is required.) The adjustments on the "Notes" tab of the "Properties" dialog are primarily there to adjust the note in relation to notes in the same chord but on different layers, so that the chord and its accidentals will line up properly.

Select a note/chord and then Cntl/E. One of the options is "Extra Accidental Spacing" in addition to "Extra Note Spacing".  This comes in handy when notes/chords on different staves are layered and the accidentals or notes are on top of each other.  If you download the first attachment from this thread, this page fixes the note collisions upstairs and accidental collusions downstairs.

If your intent is to tuck an accidental above/below a second interval, extra note/accidental space won't help.
Text can be used if you don't care if it highlights during playback. A layer is needed if you do:

I found that the spacer will only work at a bar line.
