The Daylite extension DayliteDocs in conjunction with its companion app Docs2Daylite gives you the option to save PDF documents via the regular macOS print menu from within any app in Daylite.
To do so, please follow these steps:
- In the desired app, open the print menu via the keyboard shortcut ⌘ P or alternatively via the app's File menu
- In the PDF drop-down menu select Save to Daylite. In the background the created PDF document will be transferred to DayliteDocs and subsequently saved within a Daylite note, as describe in this HelpCenter article
