Right-Click Shizzle

The context menu pops up when you do that tap-&-hold thingy on a library (iOS/iPadOS) or right-click like a desktop person (macOS).

YEET It

This option will straight-up delete the library & literally everything inside it. RIP.

Clone That

This option makes a copy of a library so you can mess with it without destroying the original. You're welcome.

Rename It, Bestie

This option lets you rename the library. Spoiler: it also renames the folder underneath. Wild, right?
