Blocks: Some way of using a block (another note) within a note in another note (as a linked block). Such that as one note/block is updated it updates in the other note/block. Good for things like quotations, bringing forward thoughts etc. - see also earlier notes on Copy/paste blocks/notes.
So for example: one Note is a QUOTE.
If writing a comment/review one could INSERT the QUOTE into the current Note (ie. the quote text/note). And if the quote changes/origin note changes the text in the comment/review note also changes.
This would enable the possibility of creating CONTENT in a single document made up of Notes from other boards etc. – and is preferable to just including LINKS as is now the possibility.
