Merging notes needs better identifiers


Merging notes at the moment put everything together without identifying where each note comes from (see attached example of three notes captured from different sources - even individual color labels are not shown). It would be great if color coding is introduced, as well as text reference to the source of a note. This is really essential when using more than one book/paper in a notebook.

Here is an example of three notes captured from two different sources and color marked seperately:

But when merging he upper two notes, it comes up with one color only - losing the distinction between where each note comes from.
