Whole-line copies and cuts paste above the caret line from every paste entry point (shortcut, menu, history, plain text), including a copied blank line. Paste from History opens a dialog with filter, multi-select, delete and preview. Copy Path/Reference (⇧⌘C) opens a chooser for absolute path, file name, content-root/source-root paths, path with line and reference. Text pasted into a string literal is escaped (Smart Keys setting; Paste as Plain Text bypasses it), and missing imports are added after a paste (Auto Import setting: Ask / Always / Never).
