i have one question, for me emacs have only 1 major flaw (or you can call it drawback) , its slow, some extensions are very very slow , magit for me is the prime example , json-navigator is another<p>will this make emacs fast , i understand guile is a nicer language than elisp, but if its not significantly faster, this i think will go nowhere<p>(the second but minor flaw, it need better graphics, nicer ways to represent directory trees or git branches, other than ascii, but if emacs becomes fast, i can live with that)
