If the option "Open new folders in tabs" is enabled: clicking to open on the desktop a folder that is already open in Dolphin focuses that window. If the option "Open new folders in tabs" is disabled: clicking to open on the desktop a folder that is already open in Dolphin opens that folder in a new window. That is unexpected: the option to open a new folder in a tab or a window should not affect the fact that if a folder is opened in Dolphin its window should be focused instead of it being opened in a new window . Focus an already opened window/tab should always happen or, if that's not true, it's incoherent to have that focus when the option "Open new folders in tabs" is enabled: logically that focus should happen in both cases or in none. STEPS TO REPRODUCE 1. enable or disable the Settings > "Startup" > "Open new folders in tabs" option OBSERVED RESULT 1. if enabled, clicking to open on the desktop a folder that is already open in Dolphin focuses that window. 2, if disabled, clicking to open on the desktop a folder that is already open in Dolphin opens that folder in a new window EXPECTED RESULT That option should not change the fact that the window/tab of an already open folder should be focused (instead of a new one being opened) when opening that folder again.

Having a folder on the desktop called "test" which is not opened in Dolphin: double clicking it a first time opens a new tab or a new window, based on the option Settings > "Startup" > "Open new folders in tabs". Double clicking it a second time should either focus the already opened tab/window (no matter the option Settings > "Startup" > "Open new folders in tabs"), or open a new tab or a new window (depending on the option Settings > "Startup" > "Open new folders in tabs"). But the option Settings > "Startup" > "Open new folders in tabs" should not affect focus.
