In ArcoLinuxD we install all our software with scripts.
Scripts can be easily edited. Delete lines, add lines. Install the software YOU like. That must be the first step to install the applications you do want.

There are two applications you can use to install and uninstall applications. I will show you both in this tutorial.
pamac and gnome-software
Both are very efficient and eye-candy.
