I'm pleased to announce the public release of a new feature, the so-called "Maths Map". Inspired by a discontinued feature at a well-known education website, this attempts to make math drills more accessible.
In terms of time to features, this may be the most efficient thing I've done for the site. Although I've had the idea of math projects on my mind for a while, work began on this, in earnest, on Thursday. That means it took less than a week to get it online.
There are a lot of things I'd like to add and improve. The aesthetics are lacking, and so is documentation. But in this case, I thought it'd be good to get it out and to add to its feature set over time.
This saves statistics, but you have to be registered and logged into your account. At present, anything you do before registering, or while you're not logged in, is not saved, even if you register or log in later.
None of this is original, but it does now appear to be unique. I hope you'll enjoy using it.
