- Better code sharing. For example, don't have to duplicate tab layout or
bookmark bar layout code.
- Tab Strip
- Drawing
- All the animationy bits
- Subtle click selection behavior (curved corners)
- Drag behavior, including dropping of files onto the URL bar
- Closing behavior
- Bookmarks bar
- drag & drop behavior, including menus
- chevron?
- Tab Strip
- Easier for folks to work on both platforms without knowing much about the underlying toolkits.
- Don't have to implement ui features twice.
- Dialogs
- Native feel layout
- Font size changes (e.g., changing the system font size will apply to our dialogs)
- Better RTL (e.g., https://crbug.com/2822 https://crbug.com/5729 https://crbug.com/6082 https://crbug.com/6103 https://crbug.com/6125 https://crbug.com/8686 https://crbug.com/8649)
- Being able to obey the user's system theme
- Accessibility for buttons and dialogs (but not for tabstrip and bookmarks)
- A better change at good remote X performance?
- We still would currently need Pango / Cairo for text layout, so it will be more efficient to just draw that during the Gtk pipeline instead of with Skia.
- Gtk widgets will automatically "feel and behave" like Linux. The behavior of our own Views system does not necessarily feel right on Linux.
- People working on Windows features don't need to worry about breaking the Linux build.
