TWiki - should use CSS, also it would be cool to translate to XML instead of HTML and use a style sheet to transform. That would make it easier to write stuff in Twiki and move it to DocBook XML.

Also, it would be cool to have a twiki plug-in that could automagically produce image galleries out of directories full of image files (i.e. thumbnails, etc). Sorta done, I wrote a small hack to build the thumbs one at a time.

Dia - UML shapes need a once-over. Add more attachment points, allow different colors, etc. Still true, but I use ArgoUML now.

Bonnie - add a make dist target to Makefile, generate GNU/Linux binaries for intel, sparc. Also output results one test at a time so you don't have to wait until the end.

sh-utils - figure out a way to XML-enable these tools. This would preserve the flexibility of text I/O, pipes, etc while making it easier to do medium-complexity processing on the output.
