Leon_Guan in order to properly support Unicode they've sacrificed a large part of the previous' search functionality. Apart from just searching from the beginning it now splits words at uppercase letters (Pascalcase). Even worse it does not use boolean AND to search for items that have to contain all words. It uses boolean OR instead and finds all kinds of unrelated items. On top of that the UI doesn't show the results within the list but in a separate window and in order to get all results you have to press CMD+Enter/Strg+Enter. Who thought that this is a good idea has probably never used any of the previous 1Password versions or something like macOS' Spotlight.
All those problems were reported more than 6 months ago but nothing has changed. They've only added the well hidden and strangely placed Find function.
Regarding re-arranging fields they've ackownledged that they initially thought this feature is overly complex and rarely used. As with many other regressions they're now resonsidering their decision. I doubt anything will change apart from some cosmetic changes. In my opinion 1PW8 looks and feels like software developed behind closed doors totally disconnected from its long term userbase.
