In VS code you can press Alt + up to place a second cursor on the line immediately above your cursor.
I think that same UX as an addition to the Alt + click Obsidian currently has would be a very good workflow improvement, and familiar for anyone who uses VS Code
A use case that you’d commonly run into is tabbing multiple bullets in a list all at once, or adding bullets to the beginning of multiple lines, or changing those bullets to checkboxes, etc.
