Dashboard looks weird when using this plugin

Right now I am making the most of free admin menu editor but I am facing Designing issues when I rename a menu with a long title. I think there has to be some proper solution. I have tried to manually increase the width of menu panel (at left side), but it is not working, at least with me. Please give me an appropriate solution. Thanks
