Additional Filter Operators

Is your feature request related to a problem? Please describe. I'm working on an internal reporting tool and wondered about the filter operators. First of all we would like to have a inNumberRange/notInNumberRange to allow an easy filter like "invoices with a gross value between x and y" similar to the inDateRange variants. Also we would like to have a afterOrEqualDate (>=) as a variant of afterDate (>) that includes the given date in the range.

While we could reproduce the number range with the given operators gt, gte, lt, lte and the logic and/or, at the moment there is no easy way to have a >= check with dates.

Describe the solution you'd like While reading the documentation about filter operators my first thought was why there are the beforeDate and afterDate operators at all. As far as i can tell those are just lt and gt with a fancy name. It would be awesome to just be able to use gt, gte, lt, lte for dates as well as numbers, and having a new [not]between operator that replaces the date range operators and can be used with number and time?
