It’s important to distinguish between style and function/layout. Breeze is just a style. Hamburger menus and FormLayout control arrangements aren’t related to Breeze; they’re functional/layout choices made by the app’s code, not something determined by the visual styling. Those things can and must be changed independently of the style.
At the moment there are currently no plans for a major visual overhaul of the Breeze widget/app style itself. We will continue to incrementally evolve it over time as we have been doing, though.
There are currently developer desires for larger changes to Breeze icons, though. For example:
- Removing the 45° shadows on colorful icons
- Broadly overhauling colorful icons in general
- Increasing stroke widths and corner roundness of monochrome icons
- Deleting the 22px icon size and using 24px icons instead, for better compatibility with GTK icon sizes
At the moment it’s mostly about finding people with a combination of the technical competence, artistic ability, and interest in helping to make these changes. Overhauling a whole icon theme–especially one as complete as Breeze Icons–is a monumental task. There are literally thousands of icons that need to be done, and you need to land the changes all at once; you can’t do a few in this release, a few in the next release, and so on.
It’s important not to underestimate how much work it takes to make large-scale visual changes to icons and app themes. It is thousands of person-hours. It’s not the kind of thing you just do because you feel like a change or because industry trends have shifted.
