Collapsing on single line?

Unfortunately not at this time. This is something that we would like to address but the main problem is that nodes are offset-based so we don't know (without a lot more processing) whether they cross lines or not. One thing we are considering for the long-term future is a switch to tracking things internally by line/col instead of offset (but still allowing you to use offsets like now). If we do that then that would enable this sort of feature to be easily implemented.

OK.

I have a workaround for my case, I was just hoping there was a better way than the way I was doing it.

Thanks,
