You can use it right away. I was able to immediately apply the material to the PPT I was presenting next week! What's disappointing is that it would be nice to be able to specify a user font. I use Korean, and the default font does not change in Korean. It’s tacky!
I wish there were more templates. It's still a lot, but it still feels like it's not enough! There are some regrets, but they are regrets because I expected further development. I don't regret the purchase!
