In the old UI. secondary inventory windows (shift clicking the active ship button in the inventory spawns a new window) does not have a triangle button on the top left that allows me to immediately open the sidebar. I have to click the options button, navigate to the show sidebar checkmark, scroll to my filter list to select what I want displayed, click the show sidebar checkmark to hide it again. This is tedious to do across multiple accounts especially when I am in a hurry. Please add a button to show sidebar in compact mode for secondary inventory windows.
