I've just found out how to add lyrics (go to Edit -> click a bar and choose to add text instead of chords/symbols). The text size is big and very readable. This works great as long as there's not many words in the text, or e.g. In fast songs. But when it comes to ballads and songs with many words per bar, the text doesn't fit on one line because it's not sizable. A way to come around the problem is to simply shorten some words, like writing svrl instead of several.
--> So a "fit text" function would be the perfect solution!

Another great function would be a "show/hide lyrics" button, whereas some both play and sing, while others play (or sing) only. That way we could add lyrics to all suitable songs in the forum and anyone not interested in seeing the lyrics could just turn off the function.

Any more thoughts?
Cheers!
