Microsoft PowerPoint on windows is getting a new adaptive Mini toolbar to help users improve their work efficiency. This feature is already online in Microsoft PowerPoint for Office Insiders running the current channel (preview) version 2005(Build 12723.10000) or later.
In order to meet the ever-changing needs of users, the development of this mini toolbar experience has not actually stagnated. Microsoft has now added three additional buttons to the end of the mini toolbar, which are calculated based on the last 20 commands used to process files. As users switch between commands and tasks, these buttons are automatically updated to suggest commands related to their current task.
Microsoft plans to release the new adaptive mini-toolbar experience to current channel (preview) users in August. It shouldn't take too long to launch to all Microsoft 365 users. You can go to the PowerPoint before the product is finalized if you are a Office Insider member and have any suggestions for this new feature
