thanks for taking notes @ManickaP. Should? we merge it to keep it with the code? |
I'll transform the comment like notes into real comments and the ones which are pointing out problems into issues. We should not merge this PR. I'll make a different one. Let's not pollute our code base with meeting notes. |
