Many  homebrew devs have cut back on the amount of releases that they are  making for the PSP recently.  But not PSP Homebrew developer OuterHeaven  who has released an updated version of All Install.  All Install allows  you to download and install a number of things for the PSP including  homebrew, plugins, themes, gameboots and version.txt's.
Changelog for All Install New Version
"New version changelog:
1) File browser now lists files in alphabetical order
2) You can copy or delete whole directories
3) Both zip and rar files can be extracted
4) Improved the plugin installer, and also created a new way to install plugins (clicking X on a prx file gives you the option of adding it to your vsh.txt, game.txt, and/or pops.txt)
5) Created a new mode for the file browser that allows you to select an almost unlimited amount of files, and then copy or delete them. In a test, I actually selected 230 individual files (which came from 20 different directories), and then copied them all to a new directory.
6) Created a color config file that allows you to change the text colors of the program. (Useful when making a custom skin)
7) MANY bug fixes and other improvements"
