making use of four separators instead of only two + allowing spaces set as needed.

The separators are meant to include the needed blanks, e.g.

--sep-2=" „" --sep-3="” (" --sep-4=")"

You might want to combine the four command line options into a single one like

--pattern "separator-1" "separator-2" "separator-3" "separator-4"

if this is possible. e.g. (equivalent to example above)

--pattern "" " „" "” (" ")"

resulting in e.g.

Email Client „Claws Mail” (Send and receive emails)
