This something I could really use: functions added to the various fields in the hole tool. I don't know if its particularly difficult to do but it seems to be the only feature box that doesn't allow it. All the hole types only only have a function box for the hole depth. But hole features are great for other things than just bolts and screws and I use them a lot for mould design. Being able to control hole features across an entire project (say, guide pillar holes in an injection mould) using global parameters would be a great time saver.
