Privacy Browser Android

Requesting the ability to download a website for offline viewing, perhaps with a management system similar to the current bookmarks, where you can group, add, and remove your offline pages. I stumbled across Save for Offline, but it appears to be largely abandoned, or at least stalled now: https://github.com/JonasCz/save-for-offline

One of the bugs opened in Save for Offline also points to the utility HTTrack (https://play.google.com/store/apps/details?id=com.httrack.android, http://www.httrack.com/), which seems to have this functionality as well, complete with working hyperlinks, however having it built into the browser would be handy for centralized management and viewing.
