If an item comprises an attachment (e.g. OneNote link) and is also a Parent, it can been seen in the Overview drawer.
These items get rendered as “links”, which isn’t entirely bad…although you can’t “follow” them by ctrl+clicking – so that is inconsistent.
Additionally, the “link” styling appears to come with its own background color, which I can’t find the source of in the theme definition.
I suggest that these items should be drawn just like any other Parent in the Overview. There is little value in differentiating items with attachments in the Overview Drawer and it will get even more messy if these items have plain text along with the attachments.
This happens using the default Theme settings.
