The ability to seamlessly animate objects from one slide to the next is one of the greatest features in Keynote.

I haven’t had a chance to look into reveal.js yet but I assume the data structure contains slide objects that contain the various elements on a slide. This could be implemented by giving ids to elements and, if the transition type is set to, for example “auto animate”, key properties of elements with the same id can be tweened (e.g., x position, y position, width, height, opacity, rotation).

I think you should make CSS editing free.

It would really help out!

Make the Theme editor available for Pro customers please.

While editing my presentation I don’t know how many slides there are and so I cannot calculate how long my presentation is going to take and where I am in relation to it.

Similarly, the presenter display does not have the current slide and total slide numbers so I cannot see how much more I have left. It is the combination of this information and the countdown timer that let’s me orient my timing when presenting in Keynote.

you need to add more animations (the few animations are so simple)
i am not a developer and i need to do more amazing presentations

You should put in your chrome book username and password and wala your in your slides.

It should be possible to add media files via pasting a URL. This way, one could e.g. easily include stuff from online resources like wikipedia, or files from github etc.

Quiero saber si hay algún modo para poder editar el tamaño de imágenes insertadas en un slide, seleccionarlas todas y que cambie su tamaño con un solo click

The ability to create any organic shape directly into the slide without having to start from a predefined shape

Make the background for images in the media library checkerboard instead of white. I use a lot of white SVG icons in my presentation which are invisible in the media library, due to the white background the media library has. Please change this background to a checkerboard pattern (like in Photoshop for example) so I can see my white images.

Image to update(replace) on all slides/ presentations.
Image to have an update(replace) option. Once the image is updated, the change to be rendered on all presentations/ slides that is using it.

I've read about thoose API's, it would be cool too see them in Slides:
1. Chrome Cast: https://developers.google.com/cast/docs/developers
2. PWA: https://developers.google.com/web/ilt/pwa
3: A2HS mobile: https://developer.mozilla.org/en-US/docs/Web/Progressive_web_apps/Add_to_home_screen

I want to know at which slide number is my student currently in, in realtime. preferrably if they can assign themselves a temporary "username". This is useful to track how fast or slow my student is in following the class. The nature of the presentation requires the student to follow step by step that i have presented in the tutorial. one slide equals one step.

Flip horizontal and vertical are very useful when arranging objects (especially duplicated ones) on a slide and easy to achieve using a simple CSS transform (until there’s an interface for it, you can use custom CSS to implement it):

Flip horizontal:

.my-object {
transform: scale(-1, 1) !important;
}

Flip vertical:

.my-object {
transform: scale(1, -1) !important;
}

This would enable us to customise the layout of the presentation display. E.g., I want to make the background dark, tweak sizes, what’s visible, their location, etc., outside of the predefined layouts.

I have two or more objects that I want to make the same size. Currently, I have to align them on top of each other and use the guides to size them.

Also, I want to know what size an object is so I can create another asset of a similar size (e.g. I’m making an SVG using outlines and I want to get the line widths just right).

If the editor exposed the x, y, width, and height and allowed the setting of these, we could position and size elements precisely.

If I am giving, for example, a 30 minute presentation, a count-down timer tells me how much more time I have left (e.g., 5 minutes). If I also know that I have 10 slides left, I know that I have 2 minutes per slide.

The presentation view currently only has a count-up timer. A countdown timer that keeps counting (e.g., in red) after it gets to zero (so you also know how long you are currently going over if you do go over) would be a lifesaver.
