Worker supports simple tabs in the directory mode. Those tabs are not completely independent and as such share the same settings like filters, sort mode, etc.
New tabs can be created by clicking the button "N" on the left hand side or pressing Ctrl+t. Existing tabs can be closed by clicking on the button "X" on the right hand side or pressing Ctrl+w.
Tabs can be switched by clicking on the corresponding tab or pressing Ctrl+PageUp/PageDown to switch to the previous/next tab.
A menu with these actions can be opened with a right click on a tab. There is also a "modify tabs" command to access these actions from any command/key binding.
It is also possible to store the opened directories of all tabs at exit and restore the tabs again in the next Worker session. Read the configuration of initial dirs section for details about how to enable this behavior.
