First off, I am glad they were useful for you. As for modifying the templates, you may make whatever changes you see necessary or needed - it is true that it has been a while since I released a new version of these, and I actually
do have a newer version which uses generics, though the design may not be what one would expect...
I will do my best to get the latest version of these uploaded the my website and then post here when that is done. Again, feel free to make the changes to your own copy of the templates; I don't devote the same amount of time to these much anymore because my schedule is such that I don't have it to give.
