When performing code reviews, it's the duty of reviewer to ensure the branch passes all tests before accepting it to be merged. The steps are the following:

## Ensure the qml tests pass

Simply run:
$ make check
And see that all tests have passed

## Perform some manual tests

All or most of the manual tests below should be automated (eg, made into qml tests). But while that doesn't happen, here they are.

5. Click on the home button
6. Check that the home screen is visible again

2. Press and hold on the launcher area to get it into editing mode
