Too many shortcomings

The application has a nice UI and the idea is a good one but the execution not entirely satisfactory.
Many URLs can not be converted to text versions and thus just open the article in a browser.
This isn’t good enough as in this case one basically only has a bookmark application, which can be done in any browser instead.
Most of the older articles aren’t text versions and therefore unusable.
Unfortunately the search doesn’t work and delivers no results at all.
The RSS functionality is extremely limited, requires the exact RSS feed link to function and offers no intelligent search,
which makes it a time consuming hassle to add feeds.
The full screen option doesn’t offer a real full screen but displays a menu and bottom bar at all times, which is distracting.
Although it is a beautiful reader it is simply not very practical or useful at all.
