The biggest thing that I’m missing is the ability to schedule a Dataflow, plus a Dataset (without Premium capacity). Now you can schedule both separately, but not in an automated sequential way.

I love the new filter experience, much better. It would be great if the filters in the filter pane could be ordered by the author.
At times there are filters that have a natural hierarchy (Region/Plant; Manager/Employee) and presenting them in the wrong sequence causes the users to become confused.

The current method of using "drillthrough" is tedious and not obvious.

I propose a new implementation of drillthrough: single-click. Instead of right-clicking on a row, table or visual and selecting form a context menu, let's have the ability to setup a row, table or visual as a single-click drillthrough.

In May 2017 Power BI Desktop started supporting creation of DAX measures when working in live connect mode to an external SSAS model: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-may-feature-summary/

Vote on this idea if you want support for calculated measures against multidimensional models too.

create multiple apps from same workspace infect from same Dataset without replicating the dataset multiple times.
only option we have now is to update the app and only one app per workspace can be created which a kind of restrict the workspace usability.
If we can create multiple apps share it with different users without creating multiple workspace ... means same dataset no dataset replication, will save the storage as well.

We really need support for custom functions in Dataflows. This is a huge limitation to dataflows today.

Need functionality to create standard usage metrics report that can show data for all reports across workspaces. Currently, metrics reports are valid only for same workspace/report but if it can be extended to all then it will be very helpful in monitoring the usage of dashboards/reports at Organization level with just one usage metrics report.

Enable full-screen mode when working on power bi desktop. Pretty often I need to display the current page in power bi desktop mode (without sync the page to office 365) and there is a space limit, some of the visualizations are small and unreadable.

Currently open a local file from Desktop is not possible and from browser is very tedious as explained on May 2017 update:

https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-may-feature-summary/#urlTables

"If you want to use file URLs, there are some limitations. They will not open in the Power BI Desktop, only in web browsers. For most browsers, you will need to right click on the link, copy the link address, and paste the URL in a new tab"

It will be great if can be improved the way to open the files in same way as with web images or files (http://).

A dashboard that is based on a pinned live page is not automatically updated when the dataset is updated.

Automatic update of Pinned Live Pages should be implemented as a feature.

Please add a basic feature with ability to rotate a text box. In many report I would like to use screen real estate effectively by having text vertically on the left allowing full height for visuals. All Office apps have this basic feature.

In September 2017 we announced that Power BI Desktop is available through the Windows Store, giving automatic updates: https://powerbi.microsoft.com/en-us/blog/power-bi-at-ignite-2017-announcing-enterprise-ready-capabilities-for-establishing-data-culture-at-scale/

If you're not able to update to Windows 10, vote for this idea so that Power BI Desktop can be made available through Microsoft Update to older versions of Windows.

The latest (Nov 2018) release of Power Bi Desktop had some really neat improvements to the Filter pane.
One missing item is the ability to sync Page level filters across multiple (not ALL) pages.

One can achieve this using Slicers but slicers take up space you have to completely hide it.

Allowing Page level Filters to sync across selected pages will therefore ensure it can be used in scenarios where the filter needs to be applied to multiple but NOT ALL pages.

Add the ability to take or transfer ownership of a dataflow to another user. Currently all I see is a message indicating only the owner can edit the dataflow. This is needed to enhance maintainability and enable enterprise level support of a dataflow if the owner is out of office or leaves the company. At least the same take ownership option that is already available with datasets.

Export to PowerPoint reveals "hidden" Pages, and the "hidden" pages contribute to the maximum of export limit of 15 pages. It would be great if:
a) the hidden pages did not contribute to the maximum 15 pages
b) the hidden pages were not revealed when exported to PowerPoint
