I have used Xubuntu 18.04 Bionic Beaver, and one of the very useful features was the simple zooming of file icons with ctrl and the mouse wheel. Because the file icons are... image previews.
Now, in 18.10 Cosmic Cuttlefish, it does not work anymore.
Does anybody have a workaround?
You can still zoom in and out in Thunar 1.8.1 which is the version present in Xubuntu 18.10 but to do so, you'll need the keyboard:
Ctrl+Shift+= pressed repeatedly will zoom in
Ctrl+- will zoom out
I couldn't find specific information about the mouse route in the release notes or in the link to Thunar 1.8.1 in the release notes.
