I'm not sure if it's a bug, or just something you haven't gotten to yet, but I've noticed some cosmetic problems with Chrome.
First, the hidden enchantment section is a bit off. It looks like the columns for the enchants or just a smidgen wider than the container they're in, and it's causing a wrapping effect.

Also the stat drop downs work the same in firefox for both new and old calcs, but they've changed for chrome.
Firefox old:
Double click on a stat dropdown (first to pull down the drop down list, second to "hide" the drop down list but still have it in focus)
Use Up/Down arrows to change stats
Final stat isn't "set" until you hit enter, or click out of the drop down box. (by "set" i mean the points available updates, and the sub-stats recalculate)
Firefox new:
Same as above, as expected
Chrome old:
Double click on a stat dropdown (first to pull down the drop down list, second to "hide" the drop down list but still have it in focus)
Use Up/Down arrows to change stats
Stat gets "set" immediately
Chrome new:
Double click on a stat dropdown (first to pull down the drop down list, second to "hide" the drop down list but still have it in focus)
Use Up/Down arrows to change stats
After one stat point change (ie. 3->4), the stat is "set" and the drop down list loses focus so you have to reclick it to change it again
I have no idea what causes either problem, or how easy it is to fix. Both are purely cosmetic and probably aren't important, but I wanted to let you know.
I love this new calc. I was wondering if the old calc was ever going to be updated with all the recent updates. I love that it'll tie into the database too, that should make it easier to get new gear into the calc since it all comes from one source of truth. Your new calc is coming along nicely, make sure you don't burn yourself out trying to rush it!
