When we first started FeedsAnywhere we wanted to create a scalable interface that was consistent from phones through desktops, but as displays moved to widescreen formats it became apparent that we sometimes scaled too far. The solution is to provide each user some control to define a maximum width.
The controls to do that are very simple. When the mouse is over the right edge of the site the mouse cursor will change and the border will have a green glow. The border can now be resized by holding a click down and dragging left and right. The new width will be saved and become you're new default.
We hope you'll like the new changes and that they will make your feed reading experience more enjoyable.
UPDATE: I forgot to add that double clicking on the right edge will expand the width to 100%.
