What (once again) a huge update! I want to thank @MetallicGoat for playing a huge role with this one, as he has spent lots of his time in not only looking for bugs or things that can be improved, but instead even contributed a lot into the development itself! It's very fascinating to see on what can be reached when working in a team, and I am excited to see on what can be reached in the future.
This is the 206th free update available for this plugin. Development is stressful and consumes lots of time. I'd be super grateful if you'd earn us a tip:
