Note also that the new layout for the toolbar is a bit borked when opening Webcat with only one tab: everything is left aligned instead of using all the width as normal, and the last button to expand a list for File manager, backup manager, video player and download manager does not show up. Opening a second tab fixes it, and afterwards even if you close the second tab and just have one, the toolbar stays correctly formatted.

[Edit] It does not happen all the time. Perhaps just when opening Webcat from a link in another application and having only one tab? Not sure, needs more testing.
