I would like to see.
1. In the panel have indicator for preload setting to red or green color by click it on top of the menu panel (before manage menu) or pop-up for the admin after log-in to manage.
I have check it out many times in the hosting cPanel and I got warning I/O Usage very high. If many user X3 in the same share hosting they don't care about it. I have many clients want to use X3.
The system maybe slow down.
2. For website frontend, I like custom scrollbar wordpress. You will see at the codecanyon.net it's make more pretty like a flash website. It can disappear.
