Maximize Or Minimize Comments
This plug-in, maximizes, minimizes, or switches all comments in a score (including any or all versions). A straightforward method for revealing or hiding your comments, since they cannot be hidden as other objects in Sibelius can.
Sibelius has come a long way, and comments are one of the biggest advances in collaborative engraving. The only drawback is that these comments are a bit obtrusive and hard to manipulate. If you want to use them to their fullest without all the hassle and clutter, this plugin is going to be a life-saver.
