This PR includes below updates to improve the behavior of preview mode on macOS:
Update a Dock icon to suit for the appearance style of macOS Big Sur.
An initial window generated by
--app
is no longer used as a preview window because of a bit strange activation behavior when opened a single preview window. In macOS, Chromium browser will try to open a new window with UI like tabs and address bars if there were no windows which were opened throughwindow.open()
. So I changed that an initial window via--app
will close immediately and Marp CLI will try to open a new initial window viawindow.open
.
