Testing - Create separate playgrounds for horizontal and vertical grammars

[thisandagain]

We need two separate playgrounds for the horizontal and vertical grammars that represent our reference implementation for each.

Maybe two separate playgrounds? I am imagining that our block implementations are going to be potentially very different in each environment.

+1 for separate playgrounds and/or code forks. LTR/RTL was a pain in the neck to get working as a switch. Horizontal/vertical would be worse. Toolbox, workspaces, blocks, fields, inject, and more would all need to be changed. My instinct is that separate projects is the better path.

Separate projects also allows you to rip out stuff from Scratch Jr that isn't used, thus reducing download size.

Sounds good to me. 👍

Agreed, especially considering that blocks will probably have the same names in horizontal and vertical.
