I use Obsidian similar to how author wrote the summary except I write complete notes for each chapter focusing on the bits that I want to remember (e.g. for the Docker book I'm reading, I add example commands and explanations). That helps me to stop at a given point and before I resume (which could be weeks later), I don't need to read the previous chapter in the book - I just revise my concise notes and then resume the book.
Edit: I thought Obsidian didn't have a Kanban board plugin but then found this[0]. Seems to be working well except when I open the board in "Preview" mode, it shows it as a nested list instead of a Kanban board (opening the node directly opens it correctly).
