3 Questions: Atahualpa 3.5.3.
 

Greetings Atahuapla users,
I recently started using Atahualpa 3.5.3 and editing it, I couldn't do 3 things (check picture to understand):
#1. I couldn't change the arrow thing in the front of the links in the sidebars.
#2. Couldn't give space before for the links in the sidebar. It works on text widgets.
#3. I couldn't change the button thing when making a list.

Here's the picture:

I don't need other explanations, just please tell me how to do these.
Thank you in advance!
Sincerely,
Andreylaur
