As a high school math teacher, I have really enjoyed the functionality of Xournal++ for making tutorial videos using my graphics tablet and OBS Studio. Integrated LaTeX is great, but I still have a bit of a wishlist of features that I haven't found as plugins just yet:

1. A proper function grapher. I used to create/import via graphfree.com, but with updates to that site it is not as user-friendly as it once was. Creating/importing from DESMOS or GeoGebra is...okay, but not as great for my use case as graphfree once was. Something more native to Xournal++ would be nice.

2. A skeuomorphic compass tool (for Geometry construction demonstrations). I know that it does have a compass tool, but students need to see how this would work with the physical device - where to place the "pointy end" and "pencil end" of a physical compass. (my old promethean board software and some other website I can't recall had one, which was great!)

Always looking to learn more about FOSS tools to improve my math teaching!

A first attempt to rasterize arbitrary 2-D functions using the signs of four sample points (one for earch corner of a pixel). It works, but it can be optimized further by using a quadtree and recursively sample the sign values using that, instead of iterating over every pixel.

#desmos is out of control. Here is my guide to all of the features I've found so far. You can make logic gates in there. You can do lists and iterate things:

They've added summation and it's a little strange sometimes how it works. This threw me. You set i to be a list and it give you three answers. It won't evaluate it if you don't set an upper bound.

I'm excited but also a little horrified that this is the new SAT calculator. It's just so feature-rich.
