1Password 8 Mac Electron App Experiment

Being a software developer for 25 years I'm interested in technology and everything you've used to create 1PW8. But as a user I care about usabality and platform integration. Sadly both of those points are substandard in version 8.
Almost every workflow I've regulary used in 7 was either removed or replaced by something else that typically requires much more user interaction than before.
Examples:
* I have only two vaults and the second one is rarely used. I never got into tags. My main feature to organize was switching categories in the sidebar. Now I have an obsolete sidebar and a category switcher that requires more clicks and even worse hides the information, i. e. I have to click to open up a list of categories, have to refocus on this list and click again.
* Search is a total mess. I've used search all the day before. In 7 I didn't had to care about how something in the vault was written. I could just type any part of a word and the result was immediatly shown. Now I get only a fraction of the results because someone at Agilebits thought it might be better to only search for full words and even than hide some results unless you hit CMD + Return. Definately a dealbreaker.
* The password generator is available in the main app and the browser plugin. But why did you remove the QR code scanner from the main app? I typically create accounts including passwords within the main application. Now I'm forced to use the browser plugin just to scan QR codes.

Regarding platform integration:
* I really don't care if you use Electron are something else as long as you stick with the most basic UI principles of the OS. Don't use a complete custom UI, i. e. on macOS windows have either 'traffic lights' in the top left corner in order to close/maximise/minimise a window or in case of modal dialogues cancel and ok buttons. They never ever have a X in the top right corner.
* macOS offers a systemwide accent color configurable by the user. Please use it.
