There is a small bug with rectangles: If the rectangle width is 320 pixels it won't show up, so the max width currently seems to be 319 pixels.

Yes, the issue occurs anytime Celtic thinks the width of a rectangle needs to be clipped, so basically anytime the starting x value plus the width is equal to or greater than 320. Celtic just ends up exiting early instead of drawing the rectangle by mistake. I've made a patch for this already and hopefully plan to release it soon along with some other optimizations I've made for Celtic

I know it's been a few months now since I made an update here, but version 1.0.1 of Celtic CE is now out! It's a relatively small update that mostly fixes a couple of bugs (like the one mentioned above) and adds stability to several commands (and I got it out just in time for the holidays ) As usual, you can download it from Cemetech (once it's approved), or if you can't wait, you can get it from Github. I hope you all enjoy the update and happy holidays, everyone!

This library sounds absolutely amazing. When I get the time, I definitely want to see what cool things I can make with it!

Something I think that would be good for the documentation would just be a list/cheat sheet for what all the det( commands do in a short version, with the syntax, maybe a "see page XX for more details". Otherwise, got it downloaded and will be playing around with it when I can!
