I’d like to propose bringing the old bevel behaviour back as an alternate “mode” for the bevel tool. Whilst the old behaviour is not as good for actual bevelling, it was a great tool for adding extra geometry and smoothing out models. It made for a fantastic alternative to sub-d modelling. If you are unsure of what I’m talking about, please follow the link and watch this video by Chris Kuhn:
So the proposal is simple. Press Ctrl+b to enter bevel mode as usual, then hit “B” again to invoke the old behaviour.
As you can no doubt see from the video, this functionality is extremely useful and needs to return. I assume this is a trivial task as the code already exists in older versions of blender.
