No worry! So, I would say the same than for the Activites section: we don’t want for now to diverge from GNOME Shell design and move it somewhere else. I’m trying to get some upstream design people to come/read here your suggestions (and you can go on #gnome-design on gimp.net IRC to chat with them). Anyway, let’s focus to get a first version of the theme on the theming part itself: icons, shadows, color scheme, transparency, more than on behaviors. That will give us a good visibility and small stepping stones where we want to be at. Then, we can revisit and discuss for incremental improvments.
We can makes some changes (if upstream agrees) on dash to dock, like duplicating the location of the menu and adding it there (just not removing them).
That’s actually not what’s happening (changing z-order isn’t supported in GNOME Shell AFAIK). The title bar is style on maximized panel to look like there is this shadow, same with unamixized style of application title and headerbar. We can play with this
Styling the Dock is possible, I’ll let the devs who volunteered to answer and give it a try
The trash on the Dock, I think some people opened a bug report on Dash to Dock to get it implemented and they had nothing against. Unsure the work started on it. The issue is about matching the file manager to show the corresponding “active” application (not Files for instance, when you are on the trash, but the trash icon). I would say the same than for the rest: let’s not focus on this in particular right now, but we can take it into account
Ack on the other changes, good luck!
