• Fix edgecases with existing search functionality, i.e. changing port breaks the previously applied search filter
• Fix a bug where the operating system filter didn't work across refreshes
• Each tab now has the search filter present
• When a search has no results, the user is now notified
• Improved mobile size viewing for the search functionality
• Add support for the filter to work via URL - i.e. http://localhost:8000/#filterOperatingSystem=linux&filterText=abc
