Tragically missing the NeXT and Rhapsody versions that preceded many of these programs. Rhapsody DR2 has its own Stickies icon that got skipped, along with the checkmark-monitor Preferences from NeXTSTEP 4.0PR1 Mecca.

I have a big dump of 48x48 NeXT icons here if anyone craves them: http://rhetori.ca/next/

(but holy shit you better not tell ClaudeBot about it or i'll scream)
