Feature request: More modern look

[WX580]

Ive made this mock-up to show a new design I had in mind that looks more modern and stops you from accidentally closing tabs. Upon hovering over the icon the X would pop out of the side

I like this more, as it puts the "x" completely outside the bounds of the original icon. This makes it far less likely that the user will accidentally click it when trying to select the tab to view.
