1.) Please offer UI-color-schemes and support dark mode. The paper/backgound should be dark, the notes and texts bright. It is much easier to work late and long with dark display. This should not affect printing.
2.) Is it possible to shorten the extention of Dorico-Project-Files? Something like .dor would be fine
1.) I actually suggested something similar but is related to the title bar color inconsistency with the theme. Your idea sounds good, and I was even thinking of making a feature request suggesting Dorico to allow users tweak the background color to lightgreen or lightyellow for the sake of users’ visual comfort.
2.) Maybe it is a trend since Visual Studio.net (probably 2002 or 2003) uses “.vbproj” or “.vcproj” as Microsoft’s first example of using long file extensions. This trend also copes with current practice which most macOS apps follow.
