field calculator: please add serial

[pcav]

One useful function to add to the field calculator is the possibility of inserting an ID (feature number), better if also specifying the starting point (something like ID, 100, to sequentially number all records starting with 100, then 101, etc.)

Changing the starting point from 1 (or 0) to a different value can be done simply by addition. There's no need to clog the GUI with additional fields.
