Hey @AndyScherzinger, code blocks with 3 back ticks are just rendered as a block with monospaced font, right?

Yes.currently I don't plan to add support for syntax highlighting that seems to be just over the top from my point of view 👍

great 👍 👍

one random test where the time is not correctly aligned:

not sure how much work it might be to improve tables? ...

I'd remove tables for the moment - from my point of view (iOS won't support it either)
I'll look into the timestamp alignment 👍

@mahibi, I removed table rendering and the time alignment issue is also present on master (this is due to the parent layout component (flex box) :( So I would ignore that one.
