&gt; I&#x27;m not sure why Arduino decided to reinvent a text editor<p>They didn&#x27;t, they repurposed the editor developed for Processing ( <a href="https:&#x2F;&#x2F;processing.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;processing.org&#x2F;</a> ).<p>&gt; instead of focusing on a plugin for a better text editor.<p>Which cross platform editor should they have focused on in 2005?
