Bookmarks and Pages
If you have multiple bookmarks saved from different states of a Power BI page, and you have many pages, and many bookmarks, there is no way to find out all bookmarks pointing to a specific page, unless checking them one by one.
This can be an important information to know, because you may want to update all bookmarks related to one page or do something with them. We implemented a feature in Power BI Helper that gives you the full list of all pages and all bookmarks. This is in the Bookmarks
If you select a page, then all bookmarks will be filtered to show only those that are pointing to that page.

Or if you select a bookmark, you can see which page the bookmark is pointing to
Column Sizes: Performance Tuning Guide
Doing the proper modeling is always a challenge in Power BI, especially when you are working on a model for a while. One of the aspects of modeling is to make sure you do not bring very heavy memory-intensive columns. We used DMVs to find out the amount of memory that each column occupies in the model.
Here is a Power BI model which has the size of …
We can open it through Power BI Helper, and in the Modeling Advice tab, there is a new section that tells us how much space each column consumes:
It is clear that the columns Prefix and Sales ID in the above list are the most expensive columns. And obviously, this is because of the cardinality of that. If we remove this column (considering that it is not required in the model), then here is the result after saving the *.pbix file:
Wow! from 107 MB down to 11MB, saving of 90% memory size just with removing heavy, but unnecessary columns.
This very simple feature can give you an idea about expensive columns for the compression engine of Power BI, and then you can control the model based on that.
