Npcscanoverlay/icicle/threatplates casting bars

Hello, anyone knows if there is a way to have all classic rares on npcscanoverlay or a similar addon? Wotlk ofc, the one i find around has only tbc and wotlk rares, but i did remember having a full one. And if there is one with chests lol never seen that but maybe on gathermate?

Also i tried using 3.3.5 icicle but it causes the game to freeze when i use spells or i enter combat, anyone having same problem?

Lastly for threatplates is there a way to enlarge or move castbars, and is there a way to fix the awful teleporting stacking mode, overlapping is terrible but at least it's usable... And sometimes it bugs and doesn't show near mobs castbars at all lol

Thanks

Edit: forgot about atlas loot enhanced, it's not working, it says i need to see the items once to see them on atlas loot... so i can only see the icon lmao
