Hey I've found that a quite good project manager in Java.
It is named ganttproject.
It is more preferred than the MrProject for Tiki because GanntProject
is write in Java, and is able to use with WebDAV to control versions,
and thus able to open, lock file and save file in server instread of mrprojects' single user.
However unluckily I myself is a C/tcl/tk programmer :~
So can't help.........
Another one.... I found a TclTk program Impress work just like
but it need Tcl/Tk plugin. Yes, I am a TclTk guy.....I said already.
