XYplorer Beta Club
if I say that most XYplorer users are those who read from left to right and scroll down to view additional pages in a document. I hope that we can agree on this, so I shall proceed... 
The way Tab mouse-wheel scrolling works in XYplorer is quite unorthodox. To move to a tab to the right of my current one, I have to scroll the wheel up and to move to the left I need to move the wheel down. Let's take a couple of other apps for comparison: Office 2007 (its Ribbon UI, to be specific) and Mozilla Firefox. Tab scrolling behaviour in both of those is exactly the opposite: to the right on down and to the left on up. One cannot help but believe that it's the de facto standard. Therefore, I'd like to see either a tweak or an option to reverse the tab movement. There is a related thread where a person asked about adding arrows for shifting tab line left and right: http://www.xyplorer.com/xyfc/viewtopic.php?f=5&t=3637
The next Tab-wish has more than just Ribbon UI and Firefox behaviour for backup, it has a law!
It's called Fitts's Law (more here: http://en.wikipedia.org/wiki/Fitts%27s_law) and tabs in Ribbon UI and Firefox follow an interpretation of this law. If you've scrolled to the left-most tab (in Ribbon or FF), then no matter how much extra upwards scrolling you do the position won't change. That's why menu bar in Mac OS is so great: it has effectively infinite height, so users can "throw" their mouse cursor upwards knowing that it won't overshoot that menu bar. It is so great that Apple have copyright and patent rights over this menu bar 
Back to XY tabs...currently, continuously scrolling cycles through the tabs over and over. There is no same "assurance" as with Ribbon UI, Firefox and Mac OS that only the left- or right-most tab will be selected. That is what I'd like to change. Either through a tweak or a tickbox in Config\Tabs, called something like "Recycle through Tabs" (enabled to preserve current behaviour, disabled to stop recycling).So that concludes it
I hope that you, Don, and others will see the desire for XY's tab behaviour to be more standardised, more in line with what's commonly expected and to improve human computer interaction. Fingers crossed that you'll pick up this tab
