Hi Nestor and Mco,
Welcome new to the forum!
1, About manually add highlights into Study-mode notebook:
2, About use it in different pieces of my own writing- each represented by a different notebook:
Since MN 3.5, every excerpt in Study-mode notebook could be drag n drop across Multi-workspaces.
Please press and hold ‘Drag’ button to see details.
By the way, we have a plan to make better drag n drop mechanism. Maybe this cross-notebook drag operation will be able to use from Document-mode into another study-mode notebook workspace as well.
Regards,
Lanco
