Would be great with a component where it possible to create a editable pivot table:)

It would be great if there was a PCF that had the same fluent editable grid but that it had the ability to freeze columns so when users scroll horizontally they can continue to see certain key columns from the view.

One issue we have is that sometimes our grids have many columns and users like to use the Export to Excel button to update the information rather than working directly in the app. They have mentioned that if the grid had the ability to freeze the first few columns sort of like in Excel, they would find it more intuitive to work directly in the application rather than continuously exporting the Excel file. 

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

It's good idea to do an PCF to get the e-sign from customer on agreement or contract, PCF contain some fields and file uploader, from CRM I click on button send pdf request a sign, customer receive an email from system asked him to sign the pdf, once pdf signed , a copy should send back to CRM, same scenario of adobe sign

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)

It would be great to convert a grid view of records with child and parent relationships to a folder view.

I saw PCF for the note attachment but a good idea could be the same for email attachment files.
