Update: Version 1.7 is out now.

This version comes with mostly bugfixes.
Most noticable is a new pulley menu entry for youtube videos called "Load in ytdl" which tries to load a non playable youtube video url with youtube-dl (mostly usable for Vevo or other DRM using videos on Youtube). The Youtube Search (Webview) has been updated to offer a long press menu which allows you directly loading the clicked video in ytdl.
Also updated was the browser cache + speed (using the same tweaks from Webcat) and user interface which now shows a self hiding back button bar.
I added a new option in setting allowing you to set the default youtube quality. This might be handy for mobile usage as you can set it to use 360p only (which loads faster and seems not to trigger the buffering issue with gstreamer from the latest SailfishOS version).
