Summary of my experience:
- The idea is very attractive: refactor C++ code with right click and no modal dialogs;
- Rename class names seem to work fine;
- Does not work most of the times. Usually global search and replace did a better job in renaming things;
- Affects VS grammar highlight. After installation, code grey out by "ifdef"s are totally messed up. Unistall the softwate, Visual Studio went back to correct grey out;
Recommended? No. I uninstalled the software after a few days.
Still looking for a decent C++ refactoring tool.
