Obsidian does not behave like chrome right now.
Chrome with 2 tabs open:
- hit cmd-w, tab closes. one tab left.
- hit cmd-w, window closes.
Obsidian with 2 panes open:
- hit cmd-w, pane closes. one pane left.
- hit cmd-w. nothing happens
Note for chrome, when you close the last tab, chrome is actually still running in the background and you have to hit cmd-q to quit the app, yes.
Almost all other apps operate this way where both cmd w closes the last window or tab and leaves the app running in the background. For example, nvalt, the archive, spotify, textedit, outlook, vscode, preview, etc.
It’s a matter of muscle memory.
