Here's why: As said, I have customized the buffer tabs preferences in a way that the tabs of *all* buffers are displayed. That's how I find this feature most useful in my daily work, as I can quickly switch e.g. from any file I'm editing to, say, an always present shell buffer. Now, if I open a lot of files (i.e. more tabs than fit in the visible buffer tabs area), it appears to me as if the least recently opened files' tabs go into a kind of "second buffer tabs list". When switching back (via C-x b) to a buffer whose tab is currently not visible, I see this "second list", i.e. the tab of the selected buffer tab and the other tabs formerly not displayed. But instead I would expect to see the tab of the selected buffer added to the currently displayed tabs and the least recently visited buffer's tab removed from the visible tabs in order to "make room" for the tab of the selected buffer. In other words: Always display the tabs of the most recently used buffers. All this may sound a bit confusing and I don't know if I expressed correctly what I mean (I'm no native speaker! ;-) ), so here's a short example: Open four files A, B, C and D, one after the other. Let's assume that the buffer tabs area is now "full", i.e. there's no more room for more tabs. Now open another file E. The tabs of B, C, D and E are visible and A's tab no longer. This is ok. Then do C-x b A. You would expect to see the tabs of C, D, E and A, but instead you see *only* A's tab! I don't know if this is really a bug or if it works as designed. Maybe just my "weird" customization is causing this. Nevertheless, I think I should report it. Markus P.S.: Sometimes I wonder if you imagined how many problems the gutter and buffer tabs stuff may cause when you introduced it, Andy. And how much time it takes to fix these! Therefore, I'd like to state (again) that IMHO the buffer tabs are a really great and useful feature of XEmacs. It has really improved my productivity and only when I have to work in no window mode or with 21.1 sometimes, I realize how much I got used to the tabs meanwhile! Please keep up the good work!
