Oops, Sorry, I just knew that I got a bunch of comments! I was so busy for the last week, so I didn't check here again.
Thank you for all of your kind words and interests! Those really encourage me a lot!
Could you link us to your simple dialogue system plugin for UE4?
Well actually, This plugin is still on pending approval. It's because I didn't followed all the required instructions at the first submission, so I had to resubmit my plugin to the Epic Games and now It's talking much more time than I'd expected...
So neither I also don't have a way to find a link to my plugin for now. But when It got approved, then I will return here and share the link 😃
Finally I managed to publish it!
Here is the link!
