I had two issues for the "New Topic" button inside the Value Goals:
The New-Topic template's Value-Goal:: field is missing {{LINKCURRENT}}.
Adding the LINKCURRENT will allow adding new topic through Ctrl+Q, but clicking on the button under #Knowledge still doesn't work. For that I don't understand why.
Although it is possible to enter/manipulate/remove items in a dataview table, I reckon it can be made more user friendly.
I came along this plugin for Obsidian: Notion Like Tables (NLT) https://github.com/trey-wallis/obsidian-notion-like-tables.
I did not test it out, but maybe you can check it out and hopefully be able to integrate for a more Notion like experience.
