Waheed Ahmed we've started working on this one. But we're doing it a bit differently. We're introducing grid system which will enable you to add more columns on right without breaking the widget alignments. You will also have the freedom of resizing widgets to any length. Take a look at the design we're working on. We will soon be implementing this for you. Thanks again for the suggestion :D

Thank you so much for your feedback. We are taking a note on this, we will try to make the workspace infinite someday so that you can effortlessly add as many widgets you want in a row. Your such feedback is valuable to us.
