Here are a couple of changes in the Rails trunk that give me warm fuzzies:
- Automatically set content type in respond_to blocks
- New configuration option to allow you to specify which template extensions won't be rendered with a layout
The combination of these two changes will save a fair amount of typing, and that's definitely a good thing. :)
Now we just need to get the default list of extensions changed in that second patch. I'm thinking .rxml would be a great fit to have no layout by default.
