I mentioned this in [ANN] Sessions.jl, A terminal-native Julia notebook built on Pluto.jl's reactive engine and Tachikoma.jl - #18 by goerz, but it likely is a problem with the underlying Tachikoma (which I haven’t tried in isolation): The (presumably forced) dark background in all of the screenshots here is an absolute no-go for me. Please respect a user’s settings regarding their fundamental color scheme, and whether they are using light-on-dark or dark-on-light
