I would like to suggest the ability to limit replacements to whole words only. Maybe a checkbox next to "Match Case" that says "Whole Words".
Example: I want to change every instance of "Prop" to "Property" but I only want to change the exact word "Prop" and don't want to include anything else ("Property", "Proper", "Proposition", etc.). This would be a tremendous time saver as you wouldn't have to review the New Name list manually and maybe miss something.
I'm new to this utility so if the product already does this, I'm sorry for wasting your time. Likewise, if this has already been suggested, then I'm just seconding the motion. BTW, BRU is great!!!! It really saved my ass this last weekend with the "Path Len Min" feature. I was moving thousands of documents from DocuShare to SharePoint and ran into SharePoint's 255-char maximum pathname limit. BRU saved me!!!
