I see, ok. Any chance of a config flag for this? I like having a linked preview pane up while editing, but I find it a bit annoying to have to close twice. Using the ctrl-w close shortcut helps somewhat.
Its not a huge deal in any case, just takes some getting used to.
On a related note, I also find opening a preview pane unnecessarily difficult – it seems there is no option for it in the command palette – AFAICS you have to use the mouse and ctrl-click the preview icon.
