ReSharper 8 Rename Parameter Sluggishness Follow

I just installed ReSharper 8 release and while working on a website project, I selected Rename on a parameter named value, entered a new name of defaultValue, and clicked Next. At this point ReSharper dug through every *.cs, *.aspx, *html, *.resx, and whatever other file it could find containing the text "value" somewhere. It then froze Visual Studio for about 10 minutes or so. I even tried clicking Cancel, but nothing happened. When it finally finished, it's asking if I want to rename 12,127 items in javascript comments, javascript strings, code comments, strings, 12,114 XML value tags in resource files, and HTML elements.

I think this has potential to be a nice feature, but at the moment it's way too aggressive and extremely slow with commonly-used names (like value) and this brings up a couple of questions:

1. Can this feature be disabled somewhere? I remember some of the older versions of ReSharper had an option to disable "rename usages in comments and string literals" but I haven' been able to find it in ReSharper 7 or 8.

2. Can this feature be significantly limited to what's it trying to "fix"?

I understand others may find this feature useful, but to me it just gets in the way given the time required to scan every file in the codebase and the significant number of irrelevant matches.
