How about on mobile? It seems incompatible with portrait mode.

Powerpoint is not compatible with mobile either.

It's software for people giving talks, not for you. the fact that people can see it online is just a bonus.

It doesn't work well being a user. Which is what i was expecting.

I don't know what your original comment was because it's been flagged. But, this slideshow did not work as I expected when I first opened the page. Honestly, if I have to think about how to get to the next slide, your software is worse than PowerPoint. Forgive me for being so harsh.

> if I have to think

It's not for you. You are not the primary audience. The user of the software is the person giving the talk. The fact that the slides are online is just a bonus.

You are not the user.

The user of the software is the person giving the talk.
