there should an option of scrolling left and right with mouse and a sidebar at the bottom after zooming the page(especially). And zooming & sidebar disappear within seconds this thing should also be changed. And lastly there is the section of pages at the left side of the screen there should be an option of hiding and when needed we can unhide it , so that we can use it on full screen , in Windows . This features is a must the app is amazing but not convenient without this features so please look into it.
