Caja drag and drop with tree view

Caja has Tree and Places views in the left Side Pane. In Ubuntu MATE 20.04.3 LTS with default Ambiant and Radiant themes it really does not highlight possible drop location.

So you have two options:

• use Extra Pane with any MATE theme which is opened by F3 and switch one of the panes to List View:

  

• install modern Yaru theme from special PPA and use your original method with Tree or Places view in Side Pane

  sudo add-apt-repository ppa:flexiondotorg/yaru-mate
  sudo apt-get update
  sudo apt-get dist-upgrade
  

  then choose the Yaru-MATE-Light theme in MATE Control Center → Appearance.

  To get the following functionality for Places

  

  and for Tree
