Why GreenLight Pro matters less than you think

The reason you should not care much (or at all) about buying GreenLight Pro builder is that you are not missing as much as you think. As explained in previous answers, GreenLight Elements are already included in GreenShift. You already have these.

What GreenLight Pro provides is the white-label builder panel ‘experience’. There are only two things that are different:
(1) the builder’s admin menu entry doesn’t say ‘Greenshift’ but instead reads ‘Page Builder’ and has a generic icon next to it, and
(2) the builder’s home panel says, ‘Welcome to WordPress Page Builder’ and you can change ‘WordPress Page Builder’ to something else via a filter function.
