 It is worth noting the new [Fido
 mode](https://github.com/emacs-mirror/emacs/commit/213643a890913f10bac710ca8537e8b1125941d6)
 which will be included in Emacs 27. It is basically a variation of
 Icomplete that behaves more like Ido. As such, Fido mode does not
 offer solutions to the problems outlined in the above sections.
 
+To be transparent, there are a few standard Emacs features which are
+not implemented in Selectrum (mostly because I was unaware they
+existed) but which do work in Icomplete. These include the
+`resize-mini-windows` setting (see
+[#35](https://github.com/raxod502/selectrum/issues/35)), recursive
+minibuffers, and many of the `completion-*` user options such as
+`completion-ignore-case`. I do not see any design reason these
+features cannot all be incorporated into Selectrum eventually.
