I would like to hear from you how do you make use of the Mobile App. I find it very difficult to carry on a study when you started on desktop and then during the day want to carry on on Mobile due to a lot of limitations. 
For Example: 
- Anchoring can not be done by selecting text.
 - Highlights created to go to a certain notebook does not work on Mobile. 
 
Now these are just a few things that makes mobile study difficult for me.
