On streamlining the toolbar - no need to install the script icons there - you can assign keystrokes to each of the scripts.

Will try to reproduce your error message when I get time - not something I have seen.

Generally, the scripts are posted "as is" - in the form in which I use them myself, and you are very welcome to modify them to suit your own work-flow (though you might find some of your goals are hard to achieve with the existing scripting interfaces, particularly on the DT side).
