Are Sticky Notes per chance disabled in 0.16? I've been trying to enable them in my .16 game and have had no success so far after trying the config options in both Picker Extended and PickerTweaks. I've read changelogs to see if any announcement was made about them not being ready for .16, but found nothing

Sticky notes should still be present
the items for signs are in picker tweaks, the logic for notes is in picker-extended

Nothing showing up for me either. Just installed Picker Extended, tried with both old and new maps, alt-w isn't doing anything. Is picker tweaks required to use this?

Use that for notes, better than this for notes.

I too cannot get the notes to work. The specified key-binding of alt+w was not working so I changed to ctrl+w and still no luck. Thanks @groovybluedog for the suggestion

**UPDATE I didn't realize that you could only place notes on entities, so I was trying the keybind willy-nilly. Works fine if you hover and then do the alt+w. Live and learn :)
