I have already dabbled in editing some of my prior scripts so I can continue to use them with VW 2013. My main focus, however, was customizing keyboard commands and tool keys so I could get back to being productive. I have looked at the Developer wiki and Vectolab already and will undoubtedly refer to them more in the future.
Unfortunately, though, I won't be able to jump into Python because that is only available in VW 2014 and newer versions. So, I'll just stick with Vectorscript for what little scripting I might still do, whether for practical purposes or for entertainment. My brain definitely does like to do a bit of programming from time to time, as yours obviously must, also.
