The Little Launcher is an application launcher. When you run it, a small window will appear, in which you can write the name of your application and some parameters to make it run. It is modeled after SlickRun (http://www.bayden.com/SlickRun), but runs on various platforms and does not stay in memory.
p4vaddins adds functionality to the Perforce P4V/P4Win GUI clients. It adds the ability to create a populated label in one step, the ability to display the last change list in each label, the ability to checkout a file to a specific pending change list, and the ability to save a copy of a checked out file before synchronizing. It also includes a tool for working in Robert Cowham's "publish/catchup" system (http://robertcowham.com/blog/scm/p4_auto_merge.html).
