I use a number of source code providers for different projects. Unlike the great SCC Switcher on codeproject (which is down today for some reason), this one acts like your SCC provider then allows you to choose on a check-out by check-out basis which one to use. This helps me because I switch between SCC multiple times a day and remembering to switch from one to the other works great. Check it out.
I just got this nifty little utility that everyone needs ;) It adds a hot key to paste text on your clipboard without all that HTML/WORD/Visual Studio formatting. Just plain text. It rocks if you have to paste code into PowerPoint or Word a lot (like I do).
