I use multiple monitors because I often find it very helpful to simultaneously have several windows open and visible, especially when debugging code. Object view/edit windows are presently bound to display only within the confines of the main APL session window. This necessitates a lot of switching views between open objects.
The Options/Preferences window, for example, can be dragged completely off the APL session window and onto another monitor. It would be much more helpful to be able to do that with opened functions' and variables' windows.
Is this possible? probable?
