In a previous version of Project a completed task in the task list used to show as greyed out. I liked this because visually my eye was drawn to incomplete tasks while still being able to see what had been completed.

Conditional formatting like what's available in Excel would be perfect. Id be able to create a conditonal format that says if the task is 100% complete, show with a green background, if it is between 0 and 100 (i.e. in progress) show with a yellow background, and if the task is 0% complete show with a red background.

When we try to add items from a project, it is cumbersome to ‘search’ for something specific.

It would be nice to have the list show up with multiselect- checkboxes, so that multiple items can be added easily.

It would be awesome to have the 'Outline' feature from the schedule available so that the lists can be expanded or collapsed.

And finally, ability to connect to a specific view from schedule webpart will allow admins to build several views that might just be milestones/summary tasks etc.,

The Roadmap zoom filter always returns to weekly views. The zoom should maintain or lock the last zoom settings. Each time I return to Dashboard, I must reset my zoom to see a full year.

Currently the roadmap flow only pulls in the start date and the target date from Azure DevOps items as start and finish dates for roadmap items. For user story items the target date cannot be set in out-of-the-box mode. The best would be if the dates for user stories could be pulled from the Azure DevOps iterations as user stories are prioritized in the backlog and then assigned to a sprint iteration which in turn has a defined timeslot.

Would love to have the option to mark a task as reccurring after a provided time once it's completed once!

any raodmap to provide access to external users in my project for the web projects?

Task assignments, status, and important project events with Outlook and Teams notifications. This function is currently available in Planner as well as Project Online according to the Microsoft Project service description.

It would be really good if you can extract Project online to an excel or PDF document so that it can be shared with others who dont have the access to project online

It would be great if there could be an overview where you can see all your tasks for all of the projects you are working on. This is already possible in for example Planner and Project Online.
When this is released it won't be needed to open every project separately to see what your tasks for the day are. Would be a huge benefit for us!

Posibility to set a color on bars in timeline. Possible scheme for wbs levels.

I work on several large PWA project plans and it is frustratingly slow individually adding each task into road maps by the type & search function when you are adding adding a new row item.

In some situations there is the need to have the same task over and over just because it repeats several times in the course of non consecutive dates.

It would be nice to have only one tasks and define all these different dates in this same task.

Add Excel as a datasource for Add New Row tracking data. Roadmaps are simple in nature and do not always require complex tracking of all project information. When starting to build a roadmap you may only have the high level information in a tool such as Excel. By allowing this simple creation of the roadmap it can evolve over time from a draft roadmap to a full fledged roadamp.

"Add to Roadmap" command in PWA is a cool way to add tasks and milestones to row items in Roadmap. Yet, when the user tries to add the task/milestone that is already part of the row item in a Roadmap, PWA should warn or prevent me from not doing so.

Show additional data in the search results for items you want to add. Today all you get is the task names that match. This isn't useful if you have lots of tasks with the same names. Include the task start and / or finish dates in the search results so you can see work out which task you want to add without guessing. You can only tell you guessed correctly / incorrectly when you select the task from the results then see details in the selected tasks table.

Please make it possible to add task grid from modern project using page viewer webpart (iframe) into SharePoint sites.

Move link to "Go to Project Online" to top of Project Home page (instead of bottom) so users who only use project online know where to go/have easy access and are not confused with New blank project option
