I've said this many times but the only real problem I have is the shere pain to get things to work and for uniform styling across programs. I find myself just using terminal applications because gparted's UI is SO different from Wireshark, FireFox, etc. There is no consistancy. There is no standard written. There is nothing. It's just a hodge-podge of "this looks good to me!" No standards = Confused Users
Then use GNOME Disks, which (if you're using a distro with GNOME) is probably already included: https://en.wikipedia.org/wiki/GNOME_Disks
And GParted vs. Wireshark? Of course they look different, they're completely different tools - and most non-technical users never need to look at either one anyway. But here's Wireshark vs. macOS's disk utility, for comparison: https://imgur.com/a/V9zZC
