Seems like a very good plugin but widget looks terrible

I used the plugin for a few hours and it seems to be working very well. However its widget on the website looks really bad. First, it’s not aligned with the rest of the page elements. Second, its width changes when you change currencies. Finally, its drop down menu items look bad. The previous plugin I was using (Multi Currency for WooCommerce) is the opposite, it doesn’t work very well but it looks awesome.
