Main Menu

• Hamburger Menu fixes
  
  

Home Screen

• Home Screen Title
• Hamburger Menu Icon Color
  

Event List

• Event List Navbar Icon Colors
• Event List "Search" button should set focus to textbox when toggling it on
  

Event Feedback

• User-Friendly Title
• FontAwesome Icon not showing
• Add validation - rating must be in 1..5; default is "0", which is rejected by backend.
  

Dealer List

• Move "Search" out of drop-down menu directly into navbar
  

Personal Messages

• Tapping "Personal Messages" when not logged on does nothing. Either open the login dialog or present an alert explaining the user they need to be logged on for this.

Search bar behavior in general should be adjusted, currently the text field allows for multiple lines, which does under no circumstances return a result. This should be replaced with a close keyboard on enter behavior or similar.

• Home" Fragment Title now seems to be CID, not event_title. EF25 as an abbreviation doesn't make for a good title or menu item.
• event_subtitle is missing from menu now.
• Maps don't have a group header that shows their titles anymore.
• On slow devices (tested on a Galaxy S4 Mini) swiping between maps sometimes doesn't load the map, but shows a placeholder image

• Opening the Nav Menu on the Home screen always shows the last tapped element as 'active', even though the user is on the home screen.
