Enhancement: Tool brush visibility toggle for Hammer Editor

[Wheattttt]

What would this enhancement be for?

Hammer

Describe your enhancement suggestion in more detail

Much like the visibility toggle button for nodraw, it would be nice to have a quick toggle button for the visibility of tool brushes- including clips, triggers, areaportals, etc. instead of having to temporarily switch off multiple separate visgroups for the same effect. This is actually a feature from Hammer++, one which I use quite often, so it would be nice to see it make its way here as well.
