GParted 0.7.0 is less than ideal, so am looking for something else. Is there a credible alternative?
Unless something changed recently GParted is de facto standard tool. The only viable alternative are partially CLI partially GUI tools like cfdisk.
partitionmanager is a KDE/Qt gui using the same libs GParted uses. (afaik) It is almost feature-equivalent.
As of now, it lacks support for setting file system labels on some file systems, where GParted can set them just fine.(eg. fat32) Other than that, it works just like GParted.
