But isn't Xamarin.Forms only for mobile platforms? I can't find any information about building desktop apps with it (but also my only experience with Xamarin is currently MonoGame).
Yes you're right, Xamarin Forms seems to be targeted at Windows/iOS/Android portability with a common XAML codebase. For cross-platform desktop apps the best choice seems to be something like [Gtk#](http://www.mono-project.com/docs/gui/gtksharp/] But I think the same principles would apply: the UI projects would utilize the non-platform specific code in AlephNote.App and the plugin framework etc. It would probably be necessary to have a separate Mobile UI project anyway, but it still would reuse a lot of the existing C# code.
I'm totally a beginner with Xamarin and Gtk# but I'd be willing to give this a shot. I really like how multiple backends are supported via plugins in AlephNote.
I created an issue [0] for this.
I'm trying to find time today to organize the project structure for this, so that it shouldn't be too hard to add other UI frontends.
You are more than welcome to contribute, especially because I'm also completely unexperienced with GTK# :)
