Please provide a new font style that implements the Language Dependent Rules for Capitalization in Titles of Articles. It is always a manual task to correctly change the capitalization. If Powerpoint / Word does such capitalization as part of a style then it prevents errors and on the other hand it is simplified to copy & past to non-title parts (by removing the font style for titles). Even more, the capitalization is change automatically if language is changed.

Rules of such title style:
In English, almost all first letters in all words are capitalized according common rules

In German, there is only the first letter in the first word in capital letters (beyond standard capitalization such as nouns).

Such implicit feature would make the life much easier for many powerpoint users.

See for example:

Please allow the option to replace all instances of an image in a PP document.

Currently, if you have a deck that involves a single, repeated image amongst its slides, one must change each instance of the image manually.

Use cases:
• Using the morph transition, an image changes size/crop/position across the slides. Instead of tediously replaces every instance, this option would replace all at once.
• An image is placed on multiple slides throughout the document (some could even be hidden in the selection pane). You're not sure where all of them are, but the image must be updated. You can use the "change all" option to do it in one click.

Obviously this must also apply to vectors or "graphics" as you call them.

I have mocked up what it could look like here:

To avoid confusion, right at the beginning: Obviously, you can use text fields in PowerPoint for macOS. That’s not what I’m talking about.
As a tutor, I often want the students to take notes, while I’m in the middle of a presentation. Turned out, static bullet points are a bad idea when it comes to student’s input. (Be it that some points are missing, or I want to write down the specific wording I just heard etc.)
One day I stumble upon an article stating PowerPoint on Windows supports my use case with ActiveX controls. Which is awesome! If the developer tap is enabled you can insert a text box, adapt the colouring and font size, and there you go. You can easily write inside a slide on runtime – and it even saves the input.
So, I know, you won’t (can’t) bring ActiveX to macOS. However, don’t you think that this feature will help many tutors and teachers and is worth the effort to rebuild natively on all platforms?

Don’t know If links are allowed, if so, I made a dummy slide if somethings unclear:
