I agree. There are a lot of good reasons to be able to easily alphabetize. Perhaps you missed my previous request when you searched because I used the word “alphabetize” not “alphabetically”. Here is my request, not that I received much of a response: Alphabetize/Remove Duplicates
And since I posted that request, I have found out you can remove duplicates as a filtering function in LibreOffice calc (and I am sure in Excel and the rest).
Also, as a side note, if you use Advanced Tables plugin in Obsidian, you can sort alphabetically by column, which is pretty cool.
