Hey Nick,
Some other small minor things, I noticed that on the Random world generator you can set Min iterators to 3 and Max iterators to 2 at minimum, can you please change both to 1 or 2 if 1 gives problems

And the following, but this might be a personal issue, I can only use 2GB of 8GB GPU memory:

Also it would be great if you can add some things that are in Apophysis, like (arrow)buttons for scaling/moving transforms around a certain distance and/or percentage that can be changed.
Also (but I think other people have asked) more options for randomization, like changeable min-max values and being able to select which variations should be used and some sort of forced symmetry or being able to lock certain transforms so that they won't get affected by the randomization buttons.
Pretty sure adding stuff like this would help with the popularity of Chaotica even more

Edit: There's one thing I wonder if other people have this too. It's very difficult to manually move stuff around in the editor, I have to click far outside (or inside) of the lines to be able to drag it and it's really annoying, it's always doing the exact opposite of what I want it to do. For instance, if I want to increase the size of a transform you expect you have to click and drag the arrow like thing on the edge, but I have to click approx 1-2cm under that in the dead center and sometimes that causes me to select just one of the sides instead and it will drag that, if you need an example I can make another video to explain it, maybe this is also happening because of different resolutions and multi-monitor setup?
As always thanks for your hard work you put into this!
