I will ask 2 questions this time.
There are tons of questions here about tray icons in elementary but none of them work in my fresh Elementary 6.
One of them was like this:
sudo add-apt-repository ppa:yunnxx/elementary
sudo apt update
sudo apt install indicator-application wingpanel-indicator-ayatana
But it didn't work. I had error like this:
The following packages have unmet dependencies: wingpanel-indicator-ayatana : Depends: libwingpanel-2.0-0 but it is not installable E: Unable to correct problems, you have held broken packages.
Then tried Namarupa but it didn't work too.
How can I fix it on Elementary 6?
I don't like double-click in file manager of pantheon. In Elementary 5(Settings>Tweaks),there was a option for it but in Elementary 6 I couldn't find it.
How can I enable single-click?
