I am very happy to see that new Evernote Windows app has been updated to display tags in alphanumeric order. I realize that many are clamoring for the ability to sort by tag and I do not see that capability provided as yet.
The return-to-old-Evernote improved ordering is true in two places, (1) the note listing by title, where tags appear in their own column, and (2) the note content, where tags appear at the bottom of the note. This was not true when the New Evernote 10 debuted, but I noticed it was now corrected to be sorted rather than be in the order entered.
Per the "Help / About Evernote" display, I am running Windows App:
