New Desktop app update installed an almost white user interface. There is zero contrast which is not good for the eyes. I see where some people have requested a light interface so incorporate an option to select either light or dark theme like in the Office apps.

When editing in Desktop, you have to Ctrl-Click a button to trigger the assigned action - very good. But when you have multiple bookmarks and you go into "View" mode, you are effectively in "PowerPoint Mode". When in this mode, there should be just a single click for a button (no ctrl needed).

Support the creation of DAX calculation groups in Power BI Desktop - otherwise Power BI can only consume calculation groups created in Analysis Services, whereas it would be very useful to have this feature in any Power BI model.
Even just a simple text window with a script would be fine. You can clean up the UI later.
Thanks.

Vote on this idea if you want expand/collapse on column headers in the matrix similar to what was shipped for row headers in November (https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-november-2018-feature-summary/#expandCollapse).

Enable a dark/black/gray theme for the various versions of BI; to enable ease of use.

Add a column data profile histogram in the data view for every column in Power BI Desktop. This handy feature exists in Power Query (sometimes only on sampled data).

Add this feature to Power BI Desktop as well, please.

The standard slicers have now a visual level filter, but the new filter experience does not have a similar feature. A correspondent "visual level filter" allowing to define conditions that make an item visible or not. in the new filter experience. The reasons are the same that justified visual level filter in standard slicers.

When I choose the option to show the subtotals at the bottom, I expect to see the attribute name there as well and not just on top. This is especially crucial for financial statements, like shown here: https://wp.me/p6lgsG-YC

An option to toggle between showing attributes at the bottom only or at the top as well would be ideal.

KPIs can be defined in the Analysis Services model hosted by Power BI, but there's no UI to create them in Power BI Desktop.

The icon sets feature (https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-july-2019-feature-summary/#iconSets) lets you define indicators with logic in the visual itself, but having that logic centrally defined in a model KPI lets you re-use it across visuals and even reports.

We really love the new feature of 'Composite Models' in the Power BI July 2018 update! This enables us to join custom lists with DirectQuery sources.

It would also be beneficial if this would also work when connected to SSAS Tabular in DirectQuery.
This would stronlgy improve the enterprise features of Power BI.

Text attributes can be 'searched' within report slicers. However, integers cannot. For example, if someone wants to quickly find and slice by a Customer Id, it is very cumbersome right now - lots of scrolling. A simple search by Customer Id (as an integer) within the slicer would make it much faster and a better user experience

The new ribbon introduced as a preview in the Nov 2019 release is really good, but it got rid of the Quick Access Toolbar that gave us persistent access to the Save, Undo, and Redo buttons no matter what ribbon was showing.

Now, there is no save button, and Undo/Redo are in the Home ribbon only, so you cannot access them with the mouse from the View, Modeling, or other ribbons.

Currently when you use a column or measure with a category of imageUrl that has an svg image Power BI ignores the aspect ratio defined in the view box for the image and draws the image in an arbitrary square. It would be great if imageUrl would allow for rectangular images. In the case of svg this could be read from the viewbox attribute.

This would allow for the creation of dynamic databars and sparklines and other creative visualizations without having to write a full blown custom visual.

The new Modelling View was delivered in Nov 2018 and is fabulous. There is already a button to select all measures in a table - great. I would like to then move all the selected measures to another table, either by drag and drop or by selecting the home table in the properties list (just like you can do for formatting).

Anyone who uses PowerBI long enough has had a PBIX with 50-60 measures and it has become time consuming and tedious to mantain. In Excel you can do a quick find/replace to edit several formulas - in PowerBI you need to select each one individually. An "excel-like" interface for editing measures would save a lot of time! This would take PowerBI to the next level regarding productivity. I've prepared a mockup for this as well as a DAX Editor. Let me know what you think.
