Don't know if this issue is already known. Did a forum search but found nothing.

Create a note on the nav-tab with multiple lines, like:

"Hello,
this is

a test"

Then look at all your nodes via the "List Nodes" button.
The node will be listet as "Hello,\nthis is\n\na test".

I am sure that's not intended...

Just be thankful the notes aren't presented in straight binary.
