Would be cool if there was a button here (red circle above) which opens the current file with the system default app. The button could be labeled _Open with Default Program_, and have an icon that has an open folder and an arrow.
Perhaps I'm missing a quick way to do this already, but sometimes when I open an image with the DOpus viewer, I want to immediately open it in its system-associated app (eg. Photoshop). Currently, I have to close the viewer, and **Alt+Double Click** or right click and **Open With**...
Bonus suggestion: Add this functionality with a new item in the File menu of the viewer as well.
Bonus question: is there a way to add custom button currently to do this?

You can edit the viewer's toolbar and menus (and hotkeys) to do this.
The command you want for the buttons/menus/hotkeys will be one of these:
```nohighlight
FileType ACTION=shellex
```
```nohighlight
FileType ACTION=dblclk
```
(They usually have the same result, but work in slightly different ways. The first is more like double-clicking a file outside of Opus. The second is more like double-clicking a file within Opus.)
