A much requested item is a rich text editor in Dynamics CRM. You can already find some RTE experiments via CCF on the web.

Ideally, we would have a RTE that stores data as richt text (html) but also as plain text. This way, the info can be used to show in views and can be used in Excel exports or reports as well.

Project Online is being retired in September 2026.  The alternative Project Portfolio Management solution is a model driven app.  However, there is no viable alternative with a model driven app to replace the functionality we are losing when it comes to the Gantt bar customization options. In Project Online's Project Center, we are able to view all projects in a customizable table to show any project level fields we choose on the left and customizable Gantt bars on the right. The Gantt bars for each project can represent any custom start/finish fields we choose, can be represented as a top bar, middle bar, bottom bar, top line, middle line, bottom line, etc. and multiple custom start/finish fields for a given project can be combined into one Gantt bar.  For example, the start/finish can be a bottom bar while the baseline start/finish can a top bar.   

There is an "Add Picture" control in Canvas Apps which allows the user to select pictures from mobile's photo gallery. The need is to be able to have an "Add Video" control to allow the user to select the video directly from the mobile's phot/video gallery. Currently, the pain point is that if we have to upload a video, we have to do it as if attaching a file. Hence the video has to be selected from the phone's file explorer which makes it hard to find the video.

I think it would be interesting to have a calendar component when we can select and start and end date. Without the need of having to calendar object for start and end each.
I saw it is available in model driven but not in canvas app

Develop a custom image carousel component to showcase a collection of images with navigation controls for a visually engaging user experience.

Display options as radio/switch buttons for MultiSelct Option Set in Dynamics 365

Handling Queue Items is quite frustrating and requires a lot of clicks - an easy way to move Queue Items from Queue to Work or another Queue would be helpful. Maybe like a kanban board. 

There is already a multi-select-control for n:m-relations, but none for a "connection". The benefit would be to be able to add connections in the quick-create dialog (which does not support grids)
