<p dir="auto">I use my <strong>File Encoding</strong> setting as <em>Windows 1252</em>, because I mostly use this kind of file with Atom. And every time I open a large file (let's say 500Kb size, 10k lines), Atom freezes. After a while Atom displays that <em>keep waiting / close</em> window, and sometimes it will load, sometimes not.</p>
<p dir="auto">Atom always open the file as <em>UTF-8</em>. I noted it because I can see the erroneous characters instead of  accented words, and then it <em>changes</em> the encoding to <em>Windows 1252</em>. If I use <strong>File Encoding</strong> as <em>UTF-8</em>, the file is opened almost instantaneously (but with that erroneous characters).</p>
<p dir="auto">It should avoid the <em>UTF-8</em> loading step, and directly open it as the defined encoding.</p>
<p dir="auto">I noticed this morning, that on OS X, Atom refocuses the application while starting up.</p>
<p dir="auto">This means that if I CMD+TAB to another application while waiting for Atom to launch, Atom immediately grabs the focus back again.</p>
<p dir="auto">And if I CMD+TAB again, Atom keeps grabbing it back again.</p>
<p dir="auto">It would be great if these startup issues could be fixed quickly, especially the issue with Atom opening an untitled window all the time.</p>
