GParted is one of the best partition editors you'll find for GNU / Linux. You can use it from the app or from a Live if you prefer. Be that as it may, its simple interface and the powerful options that compose it make it one of the most complex software in this category. In addition, it can be used to solve some problems with partitions, partition tables, etc.
It is present in most software repositories of the distributions so that you can install it easily with the corresponding package manager or from the application stores. Well, if you already know him, you should know that he has already left the new version GParted 1.1.0. New fruit of the intense work of its developers to provide us with an even better tool than it was in previous versions.
Curtis Gedak has released this GPated 1.1.0 that you can download to install from now on, with this new maintenance update in which some patches have been included for fix bugs, improvements for the translation of the program in certain languages, and even some new improvements. Changes include an adoption of faster minfo and mdir for reading sudo from FAT16 and FAT32 formatted partitions, as well as the ability to calculate the size of JFS partitions more accurately.
Also, this GParted 1.1.0 release includes support for recognizing ATARAID, detect its busy state, and improve the movement of the LUKS encrypted partition. A necessary xvfb-run dependency has even been added for the make check and make distcheck tools during the build process of this software if you use the sources.
As for the the errors that have been solved You have several problems that some users have reported or that the development team has discovered since the previous version was released. Messages that were launched during use or that prevented it from working properly in some cases.

In case of using plasma, I recommend using kde's partition manager (in many distros the package is called partitionmanager) instead of this.
There are a lot of people out there who don't even know it exists since everyone is hyping gparted. Although they are based on the same library, it seems much friendlier to me and has certain extras typical of the kde world and because on some occasions it has gotten me out of trouble (especially with pendrives that go in fat32) than not even windows could repair and that which is a file system of your world.
In the use that I have given to both, which has not been too true either, the plasma one seems more competent to me but hey, the colors have been made for tastes.
