Annotate - Image Annotation Tool

Annotator is a neat little Flatpak tool that one can use to annotate images.

Steps

Install Flatpak if you haven't already.

Run the following command to install the Annotate Flatpak:

sudo flatpak install \
  https://flatpak.elementary.io/repo/appstream/com.github.phase1geo.annotator.flatpakref

Launch the tool with:

flatpak run com.github.phase1geo.annotator &

I would suggest setting up an alias or command in your $PATH to run this.
