Great app with a few request

Id like to request a few add ons if you think that they are worthy.
1. The ability to take a picture of the metals being quoted along with the total value for later review. The "Log" could save the pic, the time, Metal price, Weight, unit, purity, Percentage, total price., This could be saved as a offer or a completed purchase.
2. The ability to set the value of the karat such as 14K instead of .585 I could set it up as .580 to hedge against solder etc in the gold.
3. The ability to add more choices in the metals such as 16K for dental. .400 & .900 for silver coins. A feature that would allow us to place a choice on the "wheel" and also tie a % to it would be great.
4. The app should refresh the price each and every time a unit/purity etc is changed and should not have to touch the price to make it refresh.
4. The ability to hide the "persent" (Percent is the proper spelling) of Spot price, the number should be able to be selected on a wheel from 0 to 100 in 5% increments.
5. Would like to be able to set the Percent in a admin area where each metal could have a different percentage if requested.
Thanks,
Phil
