Package name: retext (TODO: check)
TODO: Windows version still iffy?
ISSUE: Open one RST file. Open another RST file. Should open in new tab in existing window, instead opens in new window. (Related: if already open, should activate that tab rather than open again.)
ISSUE: Suggestion: make bullet markers bold (that is, if I type * an item, the star should be bold to indicate it has been recognised, similarly with numbered lists)
