The performance hit was just too much, and since I got a reply from JustCode I will give it another try
What my instinct is telling me is that I (subconsciously) expect tools like ReSharper (and JustCode) to improve VisualStudio and to make it faster, simpler and more efficient.

And that it is innovating on the wrong direction (probably listening too much to its user's crazy requests)
