just a minor comment on the white space. it would be good to make this transparent so it would be well placed with darker backgrounds

[samet-akcay]

same as above.

Only the borders? Because if background would be transparent, then the arrows wouldn't be properly visible.

Hello, is there a chance to see this PR merged soon ? I'm trying to use tilling but without succes.
Many thanks for your great work !

Hi @kubikub, it is blocked by this issue. We need to create a new pipeline interface to run benchmarks, hpo, and tiling etc.
