I think it would be good if the connections in a toolchain could break at some points and bypass blocks instead of directly connecting inputs and outputs. Something like what is available on the beat platform. The reason is that even though it is more convenient while making a toolchain to just connect an output to an input it is very difficult to understand what is going on when you look at an experiment using that toolchain, specially when the experiments get bigger and the connections are crossing each other. Even if there was a mechanism to highlight a chosen connection in the experiment page can be really helpful. This mechanism is already there when making a toolchain but not when you look at the experiment.
