Spacemacs layout and eyebrowse layers

The “layout” layer is quite confusing. It is basically meant to offer an option to isolate a set of buffers and configure a set of windows.

This is the workflow I have that seems to work for me (nb: I'm using most of the time projects in their own frame):

Creating:

al3xandru

javascript:(function({
  var INSTAPAPER=true,w=window,d=document,pageSelectedTxt=w.getSelection?w.getSelection():(d.getSelection)?d.getSelection():(d.selection?d.selection.createRange().text:0),pageTitle=d.title,pageUri=w.location.href,tmplt="";
  tmplt="From ["+pageTitle+"]("+pageUri+"):\n\n";
  if(pageSelectedTxt!="") {
    pageSelectedTxt=">%20"+pageSelectedTxt;
    pageSelectedTxt=pageSelectedTxt.replace(/(\r\n|\n+|\r)/gm,"\n");
    pageSelectedTxt=pageSelectedTxt.replace(/\n/g,"\n>%20\n>%20");
    w.location.href="nvalt://make/?txt="+encodeURIComponent(tmplt+pageSelectedTxt)+"&title="+encodeURIComponent(pageTitle)
  }
  else {

         pu=w.location.href,
    isGMail=w.location.host.match(/mail\.google\.com/),
