If you add other classes to the player's div, then those disappear the next time you save the player.

Like this:
<div class="image image-left dmxHTML5VideoPlayer applicious" id="vidPlayer1">
</div>


When I save it again, it changes to:
<div class="dmxHTML5VideoPlayer applicious" id="vidPlayer1">
</div>


Is this a bug or am I doing something wrong?

Hello Jonas.

If you need to add positioning to the video player, create nested div instead. You can't change the html structure of our extension.

for example:

<div id="imageleft">
<div class="dmxHTML5VideoPlayer applicious" id="vidPlayer1">
</div>
..............
</div>
