Recently I have realized that the app lacks a possibility to open menu in hidden action bar mode. The modern phones lack a menu button. And didn't know about this problem because I have a rooted phone with custom room and use one of the hardware buttons as a menu one.
So in this version if action bar is hidden, the menu opens by the tap on any (non link) space in article text.
I also added two items in the article menu to toggle full screen mode and action bar visibility
And one more thing. There is a new option in advanced settings not to reload full text in "with tags mode" after each editing. The article view update occurs quicker in this case. It should speed up complex page text setup, especially loaded via Web search in cases where we can't definitely set the full text root and should hide the parts of the text.
