Appearance Suggestions: Transparence, Gesture to open notification shade

[jyotiradityatiwary]

Hi. Your launcher is great. Just had a few suggestions which would make the app more pleasing to the eye.

1. Make the navigation bar and status bar transparent (or add an option to hide the navigation bar alltogether)
2. Make the 'all apps' screen transparent, or instead of solid colour, show a blurred version of the wallpaper behind the list of apps.
3. Add an option to change the size/color of the date/time widget or to hide it altogether. In lighter wallpapers it becomes almost invisible.
4. Though this not a visual enhancement but still it would be great if we could assign the 'swipe down' gesture to open the notification shade.

I implemented 1. and 2. as part of my fork.
Since many of the changes I made are a matter of taste (and this repo doesn't seem to be actively maintained any more) I decided not open a PR but just publish it as a separate app.
