There are several issues you have touched on. As far as the default window title is concerned, I think it should identify the device (some of them do not identify themselves as I discovered when running "make test_interactive"). I also like what the wxwidgets device driver does which is to add some information about which fundamental version of the device driver is being used. I don't think there is such a fundamental choice for any other interactive device, but I thought I should mention it for the wxwidgets case. I think adding the prompt "Press enter or right click to continue" to the title is probably overkill for xcairo. I lean instead toward outputting that prompt _once_ (for all interactive device drivers) to stderr. You may also want to add some information about terminating the device as well to the stderr prompt for all interactive devices. I like your idea of honoring -plwindow for all interactive devices. However, plargs.c should be changed to no longer hide that option and also to change the string describing that option (which is too Tk specific now) that is displayed by the -h option. One additional question is whether -plwindow will completely overwrite the default window title for each interactive device or append to it. I lean toward complete overwrite. Also, I wouldn't bother with any of the interactive devices (e.g., gcw, ntk) that are already deprecated. And I would leave the required aqt changes to Hazen, and required wingcc changes to our Windows developers since you don't have access to Mac OS X or windows. That leaves "just" the xcairo, qtwidget, tk, wxwidgets, and xwin interactive devices to wrestle into some sort of common system for how default titles, prompts, and -plwindow are dealt with. I have made some suggestions about what that common system should be above. I don't feel strongly about any of those suggestions (except the self-identification one), but it would be great to replace the mish-mash we have now in the way we treat titles and prompts for our interactive devices with some more consistent system.
