Subject: [PATCH] feat: add follow_cursor_on_buffer_switch option (default
 false)

With this option disabled (the default) flow will not change the buffer
position at all when switching active buffers. Enable the option to
return to previous behaviour where the cursor is always scrolled into
view.

closes #271
