Add spreadsheet style ability to count numbers inside square brackets within a node or sub node.
This idea would be handy for budgeting minded shoppers. Eg. Fruit salad [$4]
Like a spreadsheet it will count in a column or child node. This could be a toggle on/off for each new child node if you want it active. [$X] an open and closed bracket is needed along with dollar sign for each line in child node to be counted if feature activated.
People could use this for calculating travel plans for example. Dropping in and out of the child node list items to fine tine costs. Would save alot of time having to manually calculate.
