Hi, it seems that I still have problem sending patches. Probably it is too big, so please get it from here: http://gorgias.mine.nu/xpromptCompletion.patch With this patch we are almost there: now completions and history work as expected, or at least I hope. Please try it and report problems. If the completion list doesn't fit in the screen, the list will not be scrollable (whós going to scroll so many entries, BTW??). While I would like not to change the API, the configuration can still be modified. To configure your prompts use field labels. That should protect you from major refactoring. Es: myconfig = defaultXPConfig {bgColor = "red" } Hope you'll enjoy. Andrea
