What applet is missing when I try to select hotcorner 'expose all windows'?

I don’t have that. Do I need to install it?

It is installed automatically with Ubuntu Budgie unless you did a minimal install.

Look for budgie previews via budgie welcome - software - budgie extras

I did a minimal install. Also, it looks like you’re talking about the Previews applet which doesn’t resolve the issue.

Previews is no longer an applet, but a mini-app, also in 21.10. If you activate it, the message goes away and hotcorners performs the action.

I’ve installed the Previews mini app from Budgie Extras, but Expose isn’t working and I get the message about a missing process if I change the Hot Corner action. I logged out, but that didn’t seem to help.

Look for previews control in your menu - run the app and tick the checkbox to activate it.

Finally! Thank you! Preview Controls shows up in the menu after installing the mini app. Much appreciated!
