Feature request: 'Refresh Template' button on Script Editor tab

It would be nice if there was a simple way to refresh templates on the Script Editor tab. 

At the moment, when I make a change to the templates file, I have to go to the Templates tab, click 'Refresh', find the template, and select it, and then go back to the Script Editor tab to run it again.  One could always use the 'Edit Template' button, but then you have to copy any changes you want kept into the templates file (plus, I prefer using my own editor for making changes).

It would be especially nice if the refreshing preserved GUI settings for any GUI components that are unchanged.
