Use case or problem
I do a lot of my work on my phone and soon my Android tablet, and use regularly a combination of Calendar and Chronology. This works well on my PC, but on my phone the right sidebar shows only one item, with PLENTY of space below. Could we use it, please?
Most modern phones and tablets have significant real estate (often more than older laptops) that we could use in the left and right side bars, currently limited to one item. 
Proposed solution
Create 2 to 3 vertical slots for each of the sidebars, configurable in the mobile menu.
Current workaround (optional)
I use the arrows and try to memorize what I otherwise just check in one go on my laptop.
