<p><a href="https://github.com/tomhughes" class="user-mention">@tomhughes</a>, based on what woodpeck said, the best options would be to disable image export controls using simple JS code (with check for current layer) when layer isn't equal to standard</p>

<p>As bonus remove unnecessary text about "Standard" layer for simplicity (so only people with wrong layer are to read this warning)</p>

<p>There shouldn't be a warning if user does things right :)</p>
