I'm curious what people think of the idea of having VueScan with one tab visible at a time (i.e. not having one group of tabs on the right and the preview/scan visible on the left, but instead one grouping of all the tabs). I've figured out how to make updating the preview and scan tabs almost instantaneous, so speed isn't an issue. Is there any particular reason to have two groups of tabs? The advantage of having all the tabs in one group is that you can display the preview and scan in more screen space, and the names of all the tabs are visible at the same time. The problem with having the preview and scan tabs on the left and the other tabs in a smaller column on the right is that the tabs don't all fit, and you need to click an arrow to display more of the tabs on the right. Regards, Ed Hamrick P.S. I just got the LS-40 scanning with VueScan 6.7.6. It works quite nicely.
