MOTION THEME - Side Menu drawer - Multiple questions for its design

[lion_no]

Trying to go for a minimalistic approach, and I'm loving the side bar to remove clutter from the front page.

Here's how it currently looks: 

Though, we have some additional design questions:

1. I'm trying to figure out if there's any way to have grouping in the side bar?
See example: 

2. How to adjust the text to be center aligned, instead of left aligned?

3. I'd like to change the "log in" to be in all caps, the current solution I've found would be to change the "LANGUAGE - ENGLISH" setting for this, is there anywhere else I could accomplish the same

Feel free to answer each question separately, as they can be marked as their own solution for each question 🙂
