Nice, but could you add percentage? For example, 120+10%=132.
And how to access history in a new tab without adding a new entry to it?
To add percentages, do: 120*1.10=132
And yeah, cannot access history without adding a new entry...yet.
Excellent one. Don't wait for crappy server connection if you don't have enough bandwidth. Keep up good work.
Simple and powerful, doesn't rely on external servers :)
