Date Slicer Improvements
1. Provide the ability to define both custom dates ranges and relative date ranges through a single slicer interacttion without the user having to switch between the types 'relative' and 'between'. The relative slicer already has a date picker icon let the user use it if selection something like "custom".
2. Provide selections like, Today, Yesterday, Last 7 Days, Last 30 Days etc... making it dead simple for users. Currently I use a disconnected dimension and 'magic' Dax, well not magic but extra work for me, to provide this type of date ranging with a single click of a slicer value

The problem is that the user cannot even switch between 'relative' and 'between' when in reader mode.
I agree with all of the above. We have many user interactions where we simply need to enter 1 date. A picker that provides a text box to enter a date along with a calendar pop up so a user can simply click on the appropriate date would be ideal. I like the idea of giving pre-defined selections like Today, Yesterday, 1st of Month, Last day of Month, but if nothing else just a simple slicer for 1 date.
this directly impacts the usability of the product as it is the most common user interaction. In addition to above we need support for quarter and last full month, last full week, etc. The key is also provided what is suggested here, the ability to choose custom and just enter a start and end date.
