I understand how to create a flow from scracth but I already created a complex main flow that I would like to organize into smaller flows.
And for the life of me, I cannot drop the already created block sequences into fnew low blocks.
If you’re referring to copying and pasting blocks and lines from your main flow into your sub-flows, you can do so by holding down shift + selecting/dragging the blocks you want to copy (cmd + shift + c / ctrl + shift c). The blocks and lines will copy to your clipboard and you can paste (cmd + shift + v / ctrl + shift + v) is into your desired sub-flow.
