Thanks for your response. The subject editing functionality was included in past versions of Evernote. I consider its removal a coding error--a Bug. How many millions around the world use Microsoft applications. Microsoft's editing functionality could be considered to be a 'Standard' based on the numbers of its users. Since all of the applications in Microsoft Office Professional use the subject functionality and Microsoft owns Windows 10, the name of this forum, my description of a Bug seems to me to be totally appropriate here. As stated previously, even Evernote's 'Search the Community' forum Search Box uses this 'Standard.' Try it yourself--copy (Ctrl-key) with drag & drop in the Search Box.
If you have been an Evernote user for any length of time, you would know that past revisions have mistakenly deleted good, solid working code. Eventually, the bugs were realized and fixed. Here, I am reporting a Bug to be fixed.
