Old-style quarter rests
S5 - Suggestion
MuseScore provides an old-style quarter rest (like an eighth rest but facing the other way; see Special Characters/Musical Symbols/Rests). Making the modern quarter rests invisible and pasting the old style ones over them as a text element is time-consuming since a score can contain many such rests. An easier/faster way use old-style rests would be a big help to those who work with early music.
One possible method (there may be others): if the Inspector is displayed while a rest is selected, the heading Rest appears at the bottom with option of selecting a small size. Add another checkbox for "Old-style quarter rest". This would be unobtrusive for those who don't need it.
