Change the Finder Window Size Permanently plus 'Open Folders in Tabs Instead of New Windows' Bug

Change the Finder Window Size Permanently

To change the Finder window size:

1. Open a new Finder window using the Finder icon in the Dock(make sure all other Finder windows are closed).

2. Hold Command and Option/Alt simultaneously and resize/reposition your window however you like.

3. Close the window.

4. Repeat steps 1-3 but instead of clicking the Finder icon in the dock, open any folder on your Desktop.

(Tested on macOS Sequoia macOS 15.0.1)

Test case 1: From the Menu Bar

Action: From Finder in the Menu Bar, select 'New Finder Window'.

Expected behaviour: Opens Finder window in desired size and placement.

Actual behaviour: Opens Finder window in desired size, not placement.

(Pass, Sort of)

Test case 2: CMD+Option+N (Keyboard shortcut)

Action: Press CMD+Option+N

Expected behaviour: Opens Finder window in desired size and placement.

Actual behaviour: Opens Finder window in desired size, not placement.

(Pass, Sort of)

Important: All these years I'd been using CMD+N to open Finder windows. I don't know if Apple changed the keyboard shortcut to CMD+Option+N or whether I'd been doing it incorrectly all this time. Either way, CMD+N still opens a Finder window for me, but with very erratic results, like small Finder windows.

That's the good news. Now, the bad news.
