if immersive reader is in word it should be in power point as well

Let the simplified ribbon be off by default. The classic ribbon is much more useful and every time I'm on 365, I change it to classic ribbon

Allow design ideas to show, even if the slide has a format other than a title page or title and content.

Reuse Slides is very handy in desktop. Most of our devices are (unfortunately) Chromebooks so we need features in Online version.
Just discovered Pear Deck add-on, which only works w/ online PPT, but to add their interactive slides, you have to download their PPT templates and copy/paste then reopen online to use them. (Their Google Slides Add-on works exactly like PPT reuse Slides, so teachers are using that instead since it's easier.

My Idea is to reminding everyone to write positive words to make everyone's day it was like " don't worry, be happy!!

add more transitions and animations as well as more designs

Instead of having to send entire slide decks or cutting down decks to just send a slide or a couple of slides add the capability to send just a single slide to someone as an attachment.

Currently the PowerPoints have animations and audio but audio does not play in Sharepoint or OneDrive, or when using embed code into LMS. Audio is a big part of our 'accessibility' drive alongside immersive reader, so would really like this enabled in Powerpoint/Sharepoint/Onedrive.

The options of inserting an audio clip and doing a custom slide show with timings are not available on ppt web.Kindly enable these options for a better experience of the users.

Sometimes when a teacher posts a document that we should do, I see that another student wrote their answers onit

Please bring back word count online. It is so much easier then having to copy and paste your text into a word counter website.

It should have option to be converted to word
File as power point files are very heavy.

Just add it and stop declining it. KIDS NEED IT FOR SCHOOL. It'll be a great hit. And it's already on normal powerpoint. I thought it would be on this too,

just do it please

Add the slide zoom feature in the online version. As explained here:https://support.office.com/en-ie/article/use-zoom-for-powerpoint-to-bring-your-presentation-to-life-9d6c58cd-2125-4d29-86b1-0097c7dc47d7

Previous versions had much better drawing tools for annotating slides while in the presentation mode. Please restore, will make online teaching/presenting much more effective.

Having only inches as the measurement unit for slide & object sizes has a huge impact on the workflow of users in all areas of the world using the metric system. Having to use a conversion tool from inches to cm is a show-stopper and will impact adoption of PowerPoint Online as a "on the go" tool for editing and creating basic content.
