Replacing Yget or including Bones in the download will become a mute point after the template changes announced here:
http://socialwebcms.com/blog/?p=48. Here's point #6 from that post:
A template manager with concepts similar to the module store. We’ll allow developers to upload their templates to a central repository - and we’ll include our templates as well. It’ll be a simple one click process - like the module store - to install a new template. When updates for your current template become available you’ll be notified through the admin interface.
For anybody following the Beta branch of the SVN, you'll see that the first 5 points made in that blog post are now finished, and I've reworked the Bones template to take advantage of the new shared templates system - in other words, it's down from over 50 files and 80 images to just 7 main files and 2 images. Yget has also been reduced to about the same number of files, making SWCMS much, much easier to design templates for. Send me a PM if you'd like a copy of the latest Bones template to try out on the Beta branch.
