I second my frustration with this. I only find out about the lack of CB support AFTER I upgrade to version 6. CB support is the entire reason I switched to Enpass in the first place. This is very annoying.
The lack of the internal browser is also breaking Chromebook support. I upgraded both the enpass app from google play and the extension from the chrome web store. The app is working but the integration to chrome is not. I can't configure the support without the browser.
