Need some help on completing my setup

[Udaba]

Hello there community!I need some help complete my install on my main desktop . Decide to switch permanently . I run Debian 10 on Gnome .I need some help on some specific tasks .

1)Im trying to make running apps visible . For example when i close (X) Steam it keeps running , i want to be able to see it and close it some how on my bar. Is this possible on Gnome?
FIXED
2)I want somehow to control my GPU fan. I have a GTX 970 and i have installed NVIDIA X Server Settings . How i can do it?

3)Is there a way , when i press my windows button dont see all running windows on gnome (i use arc menu and some more extensions) and see the something i choose?

Thanks in advance .
