Thanks for reporting, will be fixed as https://www.ventismedia.com/mantis/view.php?id=15520

Thanks for providing the related script. Middle button doesn't work with the script active.

When there are lots of tabs above so they are located on the minimze/maximize button, then it will not be possible to use minimize/maximize/close button at all. This is the same without the script too.

Nice tip, MiPi.

Middle button on tab can close any tab quickly.

ok, seems that mostly apps always show the close button for all tabs, added as https://www.ventismedia.com/mantis/view.php?id=15445
A workaround is using right-click > Close tab
or Ctrl+F4 shortcut (for active tab)

In MM4, it is possible to close tab by clicking on its ×. In MM5 × is shown only when the tab is active and hovering mouse on it. It is not a fast and user friendly way when there are lots of tabs. Please may you make it as previous version?
