I'm using Hiri in a linux env with a window manager without window decorations, so no close, minimize etc buttons..
Other programs, like browsers, can be closed with the ctrl-q keyboard shortcut. With Hiri this is reserved for "mark as read"...
It would be good to be able to customize the keyboard shortcuts.
