I just noticed after updating to Sequoia that the window title is now shown even when the toolbar is set to icon only. I couldn’t figure out what happened until I finally found this in the release notes for 3.9.7:
In macOS Sequoia, the window title is now also shown with Icon only toolbar mode.
Is there any way to disable this? Or just a hidden preference not to show the window title at all?
It’s pretty annoying even with the hidden preference for WindowToolbarStyleExpanded set to true. 
Thanks!
That‘s not possible currently as it‘s a workaround to fix toolbar issues of Sequoia.
Thanks for the info. I ended up going back to 3.9.6, and I get the previous compact toolbar with only icons and no title in the main window. I don’t see any toolbar related issues with 3.9.6 on Sequoia.
What are the specific issues to look out for? I haven’t noticed any issues in other apps either.
Thanks!
I wouldn’t recommend going back to 3.9.6 just for this. Look at the release notes for 3.9.7 and you’ll see many fixes as well as improvements.
And there are no known or reported Sequoia-related issues with DEVONthink at this time.

Thanks. I’m mostly just wondering what the toolbar-related issues are/were? As I said, I’m not seeing any issues with the old style in 3.9.6 on Sequoia. Is it possible they were fixed in later beta/release versions of Sequoia after 3.9.7 was released?
I’d prefer not to stay on 3.9.6 as well, but having the title in the main window is very distracting for me, especially as it also shows PDF properties like dimensions and page numbers, etc.
It’s not possible anymore to switch the toolbar display mode.
Do you mean just being able to select between Icon+Text/Icon only/Text only unless there’s a title?
It looks like in the main window in 3.9.6, that’s the case, but it’s still possible to add/remove/rearrange items. If I open a document/file in another window in DT 3.9.6, it shows the title as it always has, and the toolbar in the document window has options for Icon+Text/Icon only/Text only.
If that’s all it is, could I ask again to consider a hidden setting not to display the title in the main window? I’ve been rather accustom to it not being there for years, and it seems out of place since it changes with each item selected. The large display especially displays to much information (PDF info, etc).
Thanks!
Hopefully we’ll be able to get rid of the workaround or Sequoia will fix this.

Thanks for the update.
Is there an Apple developer feedback item I can vote for somewhere to help with this? I just built a minimal app with a toolbar that also reproduces the specific bug. I’d be glad to help draw more attention to it if possible.
If the bug persists through macOS 15.1, however, I might ask about the hidden setting again. 
A simple report via the Feedback.app by you (and maybe other users) might be sufficient. However, as Apple is completely focused on AI currently and 15.1 is already available for testing, I wouldn‘t hold my breath that it‘s going to be fixed soon.

I’ve filed a report with the details via Feedback.app, but as you’ve said, I won’t hold my breath.

Well, I already got a ‘resolution’ to the feedback (FB15253714), and unfortunately it is Investigation complete - Works as currently designed
There weren’t any other details.
So might I ask again for at least a hidden setting to make DT set window.titleVisiblity = .hidden?
Apple responded with the following further details just now:
Thank you for filing this feedback report. We reviewed your report and determined the behavior you experienced is currently functioning as intended.
Hiding the window title with a NSWindowToolbarStyleAutomatic toolbarStyle will resolve to the NSWindowToolbarStyleUnifiedCompact style which does not support display mode customization in general. You can manually set the window’s toolbar style to one of the other styles like NSWindowToolbarStyleUnified to support display mode customization.
I’m surprised you got a response quickly, including with any extra details.

So, following their advice, my test app now does the following in windowDidLoad:
window?.titleVisibility = .hidden
if #available(macOS 15.0, *) {
window?.toolbarStyle = .unified
} else {
// Fallback on earlier versions
}
This gets you a window without a title, with the toolbar display mode able to be changed, but stuck with a fat toolbar.
*Ignore that the sample doesn’t actually use icons for the buttons. I just used the first sample project with a toolbar I found and modified it.
Someone must have been having a good day.

Personally, I still like the unified compact toolbar style without the title the best.
But not having the title at least would be less distracting.
