I wish there was a way to turn off all the bells and whistles!!!
I like the idea of background geoprocessing as well, however the implementation does leave a bit to be desired....
I think many users would prefer something akin to a cue window... think of the download cue in modern web browsers. You issue a geoprocessing task, and the process is immediately added to a floating window with a progress bar.
There is no usable information in the scrolling bar or the results window. I have had a process running for hours and I have no idea if it is working or not, how far along, etc. I also do not have a way to cancel it without crashing it creating locks, etc. Almost 5 and out nightly updates will start, so I cannot have this processing still.
Oh, wait... I found if I right click the tool in the results window I have a cancel option. It would be nice if that was explained in the Help information on the results window.
