While I do like BufferTabs (even more since my feature requests for avoiding two rows of tabs was accepted ;)), I find pretty unfriendly how it select the next tab when I close one buffer.
For example, you open 6 files (like doing a search and replace) :
file1 file2 [file3] file4 file5 file6
The active tab/buffer is [file3]. If you close it, the editor will select the next tab in its list, but while I would expect [file4] to be selected, it select [file1], or whatever.
ie: when I do close a buffer, I would expect BufferTabs to select the tab next to the one I closed.
Well, first it work like that in Firefox. Second, when you do a big search and replace (like a tab2space), you want to close all those tabs, but if I close one modified file, then the next select buffer is (for example) another file that I had opened.
