It's this the same feature as this? https://roadmap.cintanotes.com/en/communities/1/topics/173-editing-multiple-notes-in-one-edit-window

Glad you liked it! But still will have to wait a bit I'm afraid

Thanks for the suggestion! In the next major release, the attachments will be displayed in the notes list, please see the mock up here:

Thanks a lot for the suggestion! Please note that you don't have to close the note editor to open the next note, you can simply go back to the notes list and double-click the next note to edit it. 

Thanks for the suggestion! Will definitely consider adding this as an option for V4

It's planned. However note that this idea here talks about clipping, so it will make CN into a kind of scissors tool.

Planned for v4.0

Thanks for the suggestion!
