This is a thoroughly thought-out app.
I agree with the other reviewer that there’s nothing to improve in this app. You swipe down and get three panes, which you can customize to show which panes you’re going to use. Each one of the panels can show a detail view for an item or a list view. You can use pinch gestures to open/close the detail view. You can customize this to work with either iCloud Drive or Dropbox. It has built-in smarts to not store items copied from 1Password clipboard items. The pull-down drawer is so well thought out that I can see Apple utilizing it for something of their own in the future. I love it when developers find ways to keep their app icon out of my menu bar. This app shows the icon by default, but you can disable it and only use the swipe gesture (or custom shortcut). This is clearly made by a highly-skilled, detail-oriented, developer and designer.
