Hello from the original creator of marimo. We now default to putting outputs below cells (feedback heard!). Pluto.jl was a significant inspiration in marimo’s original design.
Pluto is very focused on educational uses, and tends to be very opinioned in trying to present as little 'configuration' and optionality to users as possible, which I think makes it quite hard to use as an actual tool. It's so close to being something that I really love, but it's just not quite there for me.
Anyway, keep up the awesome work! I haven't used Jupyter at all since I started running marimo from uvx.
