Someone just PMed me, asking how to only show checked engines on my page. I thought I'd repeat my answer here, because it might help other people. You need to start by getting into the developer console (ctrl-shift-j on chrome and, I think, firefox) and going to the console. Then paste in this line and press enter:
document.querySelectorAll('table table td input[type=checkbox]:not(:checked)').forEach(e => e.parentElement.parentElement.style.visibility = "collapse");
Or you could change ":not(:checked)" to just ":checked" to only show the engines you don't have.
Couple that with clicking on the titles of the waves where you have none, to collapse them, and using the Print View: Blind Bags button at the very bottom of the page. You can also use the "Hide re-releases" option (due to a bug you need to refresh the page to update the sums) so you don't get the same engines listed over and over when they were re-released.
