One little gripe is the way that it handles large number of tabs. It unfortunately does like Google Chrome, where each tab becomes so narrow that you can't see anything but a single letter and can't find the one that you're looking for
I have attached 2 images, one showing the result in WinSCP and the other in Firefox. We can see that Firefox leaves at a minimum ~4 letters to figure out the name of the tab. In WinSCP, I have multiple tabs starting with B and I have no clue which one is which.
