So some feedback after the update: Well first of all when I logged in, I was greeted with this:
This persisted through any movement and waiting for awhile in case it was still loading. Sufficient to say, my mayor's house was "flooded" with complaints! Thankfully after a couple refreshes of the webpage it finally loaded properly.
Next up, the star menu. So it does load it faster and closes faster than before, but it still pauses a little on either of those, and still continues to pause repeatedly every few seconds. As it was barely noticeable on the test version after this update, it would seem that the amount of stuff in the star menu does increase the problem. So it is slightly improved over pre-update, but still needs more work to be decently functional
The UI resizer does persist through refreshes, so that at least is working as intended as far as I can tell.
Overall, not as improved as I was hoping for, but some improvement is better than none.
