I was using metamod pro for a while now. Happy that it could solve my problems without much fuss, just some small lines of code. However with a big site, it was taking some empty spaces in my template when it was not displaying anything. Empty spaces or weird styling if I had any assign to it. However I discovered that the pro version solves all that. I had some problems with it at the beginning (forgot to enable it, joomlaseo was breaking it) but Stephen was very helpful and hold me hand the whole time. Thank you Stephen!
