Bug 486963

SUMMARY
I turned the fourth default tab into a 2×3 layout, which worked. Then I wanted to move the process table to the top right instead of top left, but that gets reset when restarting the program. Just now for this report I tried moving the CPU graph in the "History" tab below the memory graph (so from top to bottom: label "CPU", label "Memory", memory graph, CPU graph, label "Network", network graph), restarted the program and got this layout: label "CPU", broken/empty CPU graph (despite options looking the same as the other one), memory graph, working CPU graph, label "Network", network graph. I guess the "Memory" label somehow turned into a graph? There are probably more such issues, but I will try to avoid them by just recreating everything from scratch in a new tab.

ADDITIONAL INFORMATION
In general, customisation in this new task manager is very awkward. Why do I have to have "charts" (of which some are not charts) inside sections inside columns inside rows inside pages, most of them requiring a quite precise click to open a menu to move them? And then to be able to search in the process table, I need to navigate through some very unintuitive menus to get one search bar above everything else (which might be far away from the process table) and can never have two searches in one tab. And if I want to change the update rate, I have to do it for every single element individually. Not to speak of the four bugs I already encountered when even just starting to configure everything back to how it was in KSysGuard. A settings migration script in the update process would have been nice. Same with lots of other KDE settings, many things are now reset and I will have to spend hours on getting them back.
