I like the improvement in A14 regarding the layout of the tabs--namely, it is now much easier to see which tab is selected, etc. However, the placement of the "x" used to close the tab/window is still confusing and idiosyncratic compared to other tab-based windows. Safari, Firefox, and Chrome, for example, all place the "x" directly on the tab, thus making it very clear which tab is closing when you press the "x" (or press cmd+w). If L4Mac is going to use a similar tab-based display, it would seem more natural to follow the standard tab layout and to place the "x" right on the tab rather than to place one "x" to the far right of all the tabs.
