When a transaction is split into multiple categories, it would be nice if the AMOUNT of each split could easily be increased by the state sales tax amount. Quicken used to do this years ago: when the cursor is in an amount field, you could press the "t" key and it would add your preset sales tax to that field.
Tools $10.00
—press the "t" key and it automatically changes the amount to $10.50, if in a setting you set your sales tax to 5%.
This is useful when you buy things in different categories on one receipt, and want to know your actual net cost.
I'm NOT proposing that this keeps a record of sales tax, and NOT proposing more than one percentage of tax (e.g., city, liquor, etc.)—you just enter your percentage into a setting like it's a QuickFill.
When Quicken used to do this I found it handier than the present method of having to use the calculator in the amount field and multiplying every entry by "1.05", for example.
