Doof--
I agree, it would be possible to fit the same functionality into a smaller space. As it is, though, I do a 75/25 split view with playing now and it fits fine. That's not to say we can't dream up additional functionality to wedge into the GUI.
I like the idea of some cleanup buttons, and it actually might not be as horrendously complex as it seems. (Mostly because you'd be doing the work, not me.) Some potential cleanup buttons:
--Remove top space. This would take out white until it hits words, not going into the lyrics to remove blank lines, however. You see, I'm busy cutting everything up into stanzas . . .
--Capitalize first word in line. Not only that, it would uncapitalize all other words.
--Capitalize all. This would do as promised, while offering a whitelist of articles that you might not want capitalized unless they start the line.
--Select whole line. Some way to right-click or otherwise select the entire contents of a line, so you could backspace it up to the previous line, cut/paste, etc.
Sorry to dump this all on ya, man. Your program is so good at what it does, I can't help thinking, what if it did more? I think you only really get to the end of the nightmare if you pretend to have fallen off the planet.
Doof? Doof?
