First time they open the main page (the petri dish one):
- [ ] we need to have customizable text snippets appearing in the right panel 
- [ ] the only button that will be visible will be a "next" button (arrow same as in the previous flow) to go to the next tutorial message
- [ ] at the end of the flow simulation buttons will start appearing as they are introduced to the user
- [ ] once the user finishes the flow all the simulation buttons are visible and we need to persist that they have done so

Post Tutorial flow: 
-  [ ] simulation buttons always show
-  [ ] after this flow is completed we can show random tips / facts as text (from a list) and the user can go to the next / prev
