I was a little bored last night while watching Wimpy's World episode ( sorry @Wimpy ) and
found this bash fancy menu on askubuntu
Interesting style of scripting
.
Fixed some issues, Inputing several keys triggered the menu item and removed/replaced some ANSI escape codes with hexadecimal characters.
The less ANSI the better. On one terminal it's ok but on another makes a mess.
So I thought t would make a good menu for desktopify.
Anyway here's the script:

Not sure about the wording.
Is "force desktop package install" close enough?
So save the file in the same dir as desktopify and make executable.
Then cd to that dir and run.
#!/bin/bash
# Wrapper for desktopify Misko_2083
# Menu code adapted from https://askubuntu.com/questions/1705/how-can-i-create-a-select-menu-in-a-shell-script
