I know that Logos 5 builds on Logos 4 and for many users was an update from one to the other, but would it be possible to have future installations name the folders "Logos 5"? Having folders still named Logos 4 lends to confusion when doing backups. I don't know how I can explain it better but it just seems better to have something named what it actually is.
I'd hate to be really tired one day and delete the folder thinking it's obsolete because it is still called after an older version.
