Just saw the new cowtool donation link and made sure to give back to a tool I love so much. Just a thought, would it make sense to add what the monetary value would correspond to?
Ex:
"$2 can help cowtool run for 3 hours
...
$100 can help cowtool run for X Days"
I work on AWS so I can guess what, say $5, would help in uptime. But the general public don't know if it's $0.069 a minute or $10k a month.
