It would be great to have quick access to add/remove properties without having to navigate through the settings.
There's already a button to switch between list modes (layouts). I think being also able to pick what is displayed would be great.
For example I'd like to quickly show/hide/toggle the content of the notes, or the tags, or maybe the number of words shown. In other words, bring those options closer to where they are used so we can quickly switch.
