Transferring website from iWeb to Everweb

This question maybe difficult to find an answer for. I am in the process of transferring my website which I built several years ago onto Eveweb which I've only just discovered. It does seem to have most of the same capabilities as iWeb which is great. My problem is ai can not change the size of the window on the right side which has Inspector, Assets and Widgets. This window is taking up most of the monitor making it very difficult to see the page I'm working on. Hope someone in the community is familiar with Everweb and can help. Thanks, Kathy
