title: Location for tox workdir
body: <p>If I search for class in non-project items, I get a too many matches:</p>
  <p><a href="https://i.stack.imgur.com/5Auwk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5Auwk.png" alt="ide-finds-files-in-tox-venvs" /></a></p>
  <p>All except one match are from virtualenvs in a .tox directory.</p>
  <p>I know that I can change the <a href="https://tox.wiki/en/latest/config.html#conf-toxworkdir" rel="nofollow noreferrer">workdir</a> in via the tox.ini file.</p>
  <p>Goal: I don't want my IDE to see these venvs.</p>
  <p>But, which directory to use?</p>
  <p><code>/tmp/</code> is not good, because this gets deleted on reboot</p>
  <p><code>/var/tmp</code> is not good because some team members use a Windows-PC.</p>
  <p>How to set the workdir of tox, so that IDEs don't see these files? This needs to work for Linux, windows, mac.</p>
