Although there seem to be not much development anymore on superkaramba and it may become obsolete with KDE 4. Beside of that, superkaramba 0.37 fixes some ugly bugs in 0.36 and is more advanced. (well, one of it would it make possible for me to use threads in ViewPortageX) superkaramba-0.37 still contains bugs, but less than 0.36.
Not even in the tree, so...
I refered to superkaramba-0.37-rc2. Funny, I was sure that I wrote it, but didn't. It is in the tree.
