Button back from armor grid

[Leris]

So when I open my inventory, click on my character tab, there is a button on the right to open the armor grid. However in this new window then, there is no button at all to go back to the inventory. There is no "back", there is no "X" button, nothing. I have to grab the keyboard and press "E" key again to open inventory again. Please add a button for the mouse to click, as this is the way I opened that window in the first place. Thanks!
