More options for symbol/object control
When trying to add symbols from MuseScore's 'Z' key option, I've missed some options that would improve a lot the visual aesthetics for every element in the score (just not symbols). So, the suggestion is to add the following attributes to objects - symbols, notes, clefs, articulations and so on:
1) Resize option: the user may choose the size of the object, in percentage;
2) Rotate option: the user may turn the object in 90, 180 or 270 degrees OR turn it freely by entering the angle (logically, it turns the first fixed degree options obsolete);
3) Anchor option: when entering an object, the user may change or choose another object (a note, a clef, a text or anything else) in which the inserted object will use as a reference for its position. This would be very useful even for 'crescendo' and 'diminuendo' lines, in which uses a note and the measure bar as reference for the line size instead of two notes - when you change the line spacement, these lines will become unaligned.
Hope that it may help. Thanks for the attention!
