Firstly, I would like to express my gratitude to the development team for their willingness to waste time reviewing my suggestions
The suggestions I can think of for pipeline upgrade are as follows：

1.The pipeline protected by scaffolding is modified into complete blocks, so that some special blocks (such as redstone powder, 1.14 original bamboo scaffolding, etc.) can be placed above it

2.Add a pipeline valve that can be controlled by a redstone signal switch. Some factories that rely on pipelines may need this

3.Can set the input and output priority of pipelines
The example is as follows: When I was developing a large refinery using the integrated mod "Immersive Petroleum", the production of gasoline always produced excess naphtha. If no priority was set, this could result in naphtha sometimes being input into the refinery to make gasoline, and sometimes being directly burned into the chimney, causing serious impacts on gasoline production. However, after setting the "input&output priority", naphtha could always be prioritized for input into the refinery, and the excess naphtha could be input into the chimney for burning
