Change the font, color and size of Notes
We are working to enable the resize of the Notes pane. While there is no plan to support the font type and color in PowerPoint Online Notes in the near term. Thanks for the feedback and please keep doing that.
Please take this request seriously commented
It's an accessibility issue that you have removed the option to change the colour in the speaker's notes in powerpoint (such that when the notes come on the screen in presenter view, the font can be any colour). You now have one colour (a grey-ish colour) on a black/dark grey background -- this is incredibly difficult to see, even if one increases the font size). This is anti-accessible -- many people need high contrast to read properly. Please allow white and yellow, at minimum, as two additional font colours that one can choose to have the speaker's notes written in. Why this function was removed from previous ppt versions is beyond me.
Allow text editing in speaker notes: particularly helpful for note taking in school. Highlight/ bold/ italic and font options are currently blocked on the online powerpoint format
