Some issues when inserting text
If you are inserting a title (or other text that appears in the "title" frame such as composer or subtitle) into a score and you are not viewing the top of the first page, you will not be able to see what you are typing. You should be moved to the top of the first page when inserting such text.
Also, if no note or rest is selected and staff (or a similar type) of text is inserted, a dialog box will appear. The checkbox at the bottom says, "Show this message again". This should probably be improved by changing the text to "Don't show this message again".
