The first is SCC Switcher. Not that changing your SCC provider is a big deal in PowerBuilder. But it is in other tools. Particularly if you're involved in community development work with a CVS respository like CodeXchange and also use a standard SCC provider for your day-to-day work, you may need to switch between providers for some of your other development tools. SCC Switcher allows you to do this from a mouseclick in the task bar.
The other is StampEm from KnowWare. Want to provide all of the files you're about to deploy with the same date/time stamp information? Since that's a popular thing to do, there are a number of utilities out there that do it, this is one good one.
One nice thing about both of these utilities is that the source code is available as well.
