I've had issues with the rounded corners on X11 as well. Certain windows don't appear to have transparent corners. The background of the rounded corners ends up being black or white.

Here's a small design change to maybe consider:

We have a View menu button in the toolbar Dolphin uses that's unused... what about if we condense the view buttons in the toolbar into just being that view menu button by default?

Sorry, we can't make this an option. Moving the navigator to the toolbar would require lots of changes to the code. We can't possibly maintain both implementations, it would be a nightmare.

So are we officially abandoning the idea of moving the Breadbcrumbs/URL Navigator into the toolbar? Shall we close T11663?

I vote yes.

Regarding split views, I had a thought here. Back in the day, browsers used to show tabs below the navigation bar. This created a bit of an interesting UX issue. Eventually, the tabs moved *above* the navigation bar to make things more proper. I'm wondering if both the tab bar and split view should do the same thing in dolphin. With the default dolphin layout, there are only 2 buttons on the toolbar that are 'shared' between each part of a split view ('split' and 'menu'). The rest function independently based on which part of the view is focused.

The 'header bar' look on the top of the mockup is very nice. Regarding the 'playlists' feature you mentioned, why not integrate that on the left side? Have a 'Currently Playing' or similar option that shows the songs in the currently selected playlist and then a 'Playlists' option (like in the mockup) for choosing which playlist you want?

This looks excellent as well!

Some general thoughts:

May I suggest to change title bar size from medium to little? I'm on a 169 DPI screen (very high for desktop without UI scaling) and it's still very usable

So, I've not had much time to get involved here, due to a combination of serious medical issues and needing to find a job. However, I'd like to share my thoughts on some of these UI redesigns, starting with this one:

If we leave it where it is, what I'd like to do is make it more of a distinct element so that it doesn't blend into the toolbar like it does right now. I think @manueljlin had some mockups showing that which looked pretty good.

I agree with this. I also think we should integrate the search button with the breadcrumb rather than having it sit in the toolbar, completely detached from the part of the UI it affects.

I think there were a few ideas behind moving it to the toolbar:

• Save a bit of vertical space
• Fill empty space in the default toolbar
• Looks better in general (IMO)
  
  Of course the drawbacks of this are:
• By filling the toolbar's empty space, we can't add more things to it in the future or add text to the buttons (which research shows is better for usability)
• The Breadcrumbs bar/URL navigator can get quite narrow for narrow window widths
• Uncertainty regarding how to handle split views. Divide it into two? Use only one and have it reflect the URL of the active split view?
  
  Ultimately I think it's your call here.

It seems to me that moving the url navigator to the toolbar creates more problems than it solves, because of split views.

What for? Just to be similar to other filemanagers? How many of them have split views anyway?

The window decorations in the two images are not the same.
