Settings page - Load addons lazily - #9037

In my testing with the CPU throttled the initial load is roughly on par with Vue 3!

I do have a couple suggestions though:

1. Could the group headers wait until the final count is known before displaying it?
2. On slow systems there may be many placeholders when scrolling. Could those be replaced with a single loading message?

Good idea for slower devices. Done.

All the placeholders trying to load while you're scrolling fast can be a hindrance, but I don't know of a simple way to fix this.

Ending the list after a few unloaded items with "Loading more...", if that's what you meant by "a single loading message", would have to account for collapsed groups and the variable order of list items among other things. I played around with throttling (limiting how many can be loading at the same time), but the way I did it adds the items loading to a permanent queue, even if they go offscreen before they load.

Let me know if you have any other ideas. At least a user can search, collapse groups, or filter to reduce the number of lazy items they have to scroll through.

Or a spinner. Either way I see now that it is not that easy to implement well.

For those who haven't tried it out yet, here's what scrolling through unrendered items looks like with CPU throttling active:
