The SES does not adapt to small screen well, the problem lies in the 'Project Explorer' panel, as it does not have a horizontal scroll bar on the bottom, when the width of this panel is small, the toolbar buttons and files shown inside would not display completely, as shown in the attachments. I think it's a good idea to add a scroll bar in the bottom of this panel, and collaps the toolbar buttons into a click-and-shown context menu so all buttons are accessble even when the window size of SES is small, and the width of the configuration comobox can adapts to the contents.
