Best way to enhance plugin behavior

[stephrdev]

Hi,
I recently discovered Jodit and really like it. Thanks for all the effort the community put in here!

I'm wondering what the best approach is to extend the behavior of a "core" plugin (in this case image-properties). I want to have a set of possible css classes as a dropdown. I could fork the whole project and change the implementation but maybe there is another way to get there.

I tried to base a new class on the ImagePropteries plugin and remove/add the new one but that doesn't seem right.

Can someone provide some hints on how I could do this?

If there is no better way I'll fork and provide a pull request adding a allowedCssClasses option.

Thanks!
