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

Just as with inline LaTeX equations, it would also be really usefull to have inline code.

It would be really useful to be able to fade in table cells one by one using fragments. Currently it's only possible to make the table appear as a whole but not the indidual fragments of it.

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

There's a white margin added to all presentations by default, it would be great if you could remove it or make it optional so a presentation can look like fullscreen.

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.

Reproductor de Audios. Actualmente esta el de vídeos pero no audios.

Allow to login with user-owned blockstack id and other decentralized identifiers and allow to store slides on user-owned storage (gaia hub).

Right now a slide deck using the theme.black.blue forces a #111 background color. Changing theme CSS or global CSS has no effect on this background that shows on load. I also can not seem to find how to change the play/pause button color to match the color change made on the slide navigation arrows.

Shape border can be only solid, but lines on the contrary can have dotted or dashed style. Now I am forced to "build" dotted or dashed figures from several lines. Please, allow to choose different border styles.

Allow All languages to write fully the whole time . (Full sentences to be written in one language at a time

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.

for the moment we do not have this option, and if we want to link some link we must create a transparent rectangle. It is not the best thing to add functionality. Thank you!

please extend the time of the delay animations 100 seconds is little in some slides , sometimes i need a couple of minutes.

Thank you!
