+### Dependencies

+- kitty / NerdFont

+- Archives Management:
+  - bsdtar (`libarchive-tools`) supports _Zstd_
+  - last release of `atool` is from 2012
+  - https://github.com/solsticedhiver/atool2
+  - https://github.com/wummel/patool
+
+- Drag&Drop: URI=https://github.com/mwh/dragon
+
+- Trash:
+  - `trash-cli` is a much better CLI-only solution!
+    Compare the outputs of `trash-cli` and `gio trash --list`…
+  - For `gio trash`, packages `libglib2.0` & `gvfs` are recommended.
