Right now, the tabs only have enough room for about 1 word, and this isn't enough to differentiate between some of my pages.

There is a lot of wasted space in the tab bar that could be used to display more of the title. When you aren't hovering, the pin and 'x' buttons still take up space. When there are only a few tabs, you could size them up to fix more text, then auto-resize them depending on how many tabs are open. Even shrinking the font size a little bit to fit more text would be helpful.
