Resources allows you to check the utilization of your system resources and control your running processes and apps. It’s designed to be user-friendly and feel right at home on a modern desktop by using GNOME’s libadwaita.
Resources supports monitoring the following components:
Excelent. Aggregates processes by apps so it's very easy to understand how programs are using Memory/Processor/GPU. This is better than System Monitor, that comes originally with Mint. Libadwaita theme does look a little different from cinnamon's interface, but it's not really a problem here.
Fantastic, no frills task manager-esque program. It goes in depth enough to useful, but simple enough to be usable.
