Mockup time! What could be a reasonable "middle ground" between the Mac OS design that we have today and the radical Liquid Glass design we saw this week from #WWDC25?

Disclaimer: this does not attempt to solve all the issues of modern Mac OS design, such as cramped toolbars caused by full-height sidebars and combining the toolbar with the title bar. I feel like the Apple of today is too far gone to do anything about those.

Read on to see what I actually tried to address.

@tuomas_h First question from me as a "user" would be: Can i scroll?
@seiz Yeah, this is one of those usability issues that I didn’t try to address. I also look back fondly to the beautiful Aqua scroll bars, but we’ve been living with transient scroll bars for a long time, since Mac OS X 10.7. Not ideal but not a disaster in my book.
@tuomas_h Oops. I compared it to my current finder Window but forgot, that i had changed the default setting to "always show scrollbars".
