My biggest issue with the new one (aside from the taskbar issue) is not being able to resize text. Why??
For those of you that just prefer the "old" Windows desktop app version.
This looks like a direct port:

This creates the same folder in appdata and you can even drop your old StickyNotes.snt file in there. Mine reopened with all my notes in the same spots and layouts! 1/7th the amount of RAM in use compared to the new UWP app.
I cannot verify the security or safety of this app, please install at your own risk. There is no user level install option for this app.
