On new minimal Plasma install:
There will be always someone used to have app A-Z from all the plasma group packages, you can go install one or both:
plasma
kde-applications
strange you no notice glances like @joekamprad say . + you have ātopā 
The system monitor is only required by plasma-meta. . . (I donāt have the iso open) but Iām assuming plasma-desktop was used in the download iso since a lot of the meta packages contain extras but everyone wants.
Therefore it wouldnāt end up being a required package.
That would also account for the other thread about the GTK themes being off in kde. . . I believe breeze-gtk is also in there.
If plasma-meta was used to generate the package listā¦ . Then Iām lost.
Does this mean that if I want to have Dolphin, I also have to take KFloppy (kde-applications) or other stuff, which I would then have to laboriously remove again? Please donāt start to destroy this good approach again!
For this reason, I walked away from Manjaro (among others).
Why donāt you just install the stuff you want after the basic installation is complete?
No meta packages will be required and only necessary dependencies will be installed.
OK, thatās what I wanted to hear 
You walked away from Manjaro for being . . . minimal?!? That would definitely be the first time Iāve heard someone say that hahaha
This is how it is planned
You have misunderstood me: I left Manjaro BECAUSE I WANTED A MINIMUM SYSTEM.
The minimal installation of Manjaro still had too much crap for me.
I just downloaded and tried plasma-systemmonitor
Thatās definitely not a mandatory piece of software. . . I canāt imagine that would be included for any good reason.
And yet you wanted this as part of a basic installation? And now youāre clamoring for a minimal install?
Oy, Itās time for me to head to work.
Itās simply the replacement/successor of the old KDE system monitor.
Supposedly this is now part of Plasma 5.22.4 and should replace KSysGuard in the long run.
hmm i say exactly the oppositeā¦ i only mention that you could go install the complete groups opposite to what we do when providing a minimal set of needed packages for plasma to start with adding only what you need.
Sorry @joekamprad, this is what happens when Germans talk in a foreign language. DeepL is probably not the best either
my fault ā¦
Give it a go in German - I bet heāll understand
Iām quite sure he will. 
i am not a typical German alsoā¦ and i do not use Deepl i go for this one if needed most of the time:
But I am happy that we understand each other now 
You might want to use file /home/liveuser/user_pkglist.txt to include all apps you want to installā¦
Justa quick question about the pkglist.txt - is it added in on a āneeded basis? Might be nice to feed it a āgeneratedā list from a previously setup system, if it can avoid inadvertent duplicates!
You can feed it anything from anywhere!
But (at least currently) it is a strictly manual operation.
For example, you could have your favorite apps listed in a github file.
Then simply wget that file and overwrite user_pkglist.txt before starting the install process.
