On mac, cmd-w typically closes the window when there are no more tabs in a window (e.g., google chrome behaves like this). It would be nice to have this be the hotkey for obsidian too.
Right now cmd w doesn’t do anything after you’ve closed all the panes.
EDIT: To be clear I want cmd-w to close the window of Obsidian. I don’t want it to close the entire app. On macs, you close the window but the app is still running. This makes launch faster.
