I gave up in the end and used ShareX.
It can be set up to work extremely similarly to the snipping tool, but has a vast array of other features which you may or may not find useful.
It can record screen clips. You can automate actions after taking a snip. You can upload what you have snipped for sharing... all sorts of stuff.
All free and open source. It is head and shoulders above the built in snipping tool.
Strongly suggest you take a look.
