Same sentiments here. There are some absolutely gorgeous setups, many by the same people, who often will provide the UCCW/wallpaper/launcher files for download and tutorials on how to set it up. Problems I've encountered trying to utilize them are generally two-fold. First, they're never exactly how I'd use them (apps I don't use while there are others I'd like to add) so it would be up to me to try to recreate certain widgets or functionality. Second, it seems a great majority of the designs are done using a Nexus 4 so the designs don't fit as well on my HTC One due to the real estate for the onscreen buttons that's accounted for in their layouts.I've rummaged through that site before and some of the setups are absolutely stunning. If you go into a lot of the screen shots, you can find out how they went about setting them up. The problem for me is that most of the time, they use UCCW, which is less than intuitive in how to use.
I need to do more reading on how to use it as it seems like a very powerful widget maker. I just wish it were easier to understand.
That link just put me on to Zooper Widget. Defiantly going to give it a try.
If more people like this theme and post on that page, he may upload the files with a tutorial!
