Good but still need update

1. Creator mention about backup but I dont see it, share email is there (single note). You didnt mean thats the backup are you?
2. Also I need to have sub-folders. Having one level of folder structure is not enough.
3. Please allow decimal number, when youre dealing with money at lease has two decimal number. Currently it round up or down to the whole integer.
4. Missing one important feature missing allowing to export to image.
I dont see support email so I comment here.

Vinhban about CalcNote = Calculator + Note
