There are some tools that "replace" others as a better version, but till now without replacing them, which adds to clutter. E.g. the angle grinder logically replaces the rust removal tool. But the rust removal tool is still there. Now more or less useless since the angle grinder has that function and is (hopefully) better at it. But it is a tool you have to flip through.
It would be better if you had at least an option (in options menu) that the angle grinder would replace the other tool (in radial & mouse wheel) instead of being there additionally.
