Thanks, 1P_Dave, for that reassurance. I was a software development CEO, back in the day, so I certainly appreciate the importance of paying off technical debt before it compounds and becomes something horrible (something like, y'know, healthcare or finance software).
And I hear you: in this case you were forced to ship the rewrite without a full feature set. Glad to know that things will continue to return to the product.
One feature that I'm being asked about: Will Mac users get the ability to tag multiple items? A client is a new LastPass user, and they are ORGANIZED by nature, so individually tagging HUNDREDS of items is quite tedious!
That said, please do be sensitive to making fundamental UI changes that will be most painful to your longest-term users. For example, the change to the search behavior, which wasn't extra work for you, but it sure is an annoyance for many of us! (Okay, it's extra work if you do it right: if you add a Setting to allow us to suppress this badness.)
