Would be nice if groups could use atlas textures for group icon same way icon regions do. Currently it's just displaying green squares.

Also, when first time opening /wa and selecting some large group, specially on alpha with nested groups, it causes lag spike/freeze.
Larger group = larger lag.
By default, it loads display tab of all auras inside. If you manually select group tab after and then switch between groups there is no lag at all. If you switch back to display tab (and i guess some other tab with a lot of info) and try to switch between groups it causes lag again.
I think opening group tab on group select by default would be better to deal with this lag. And if people want to edit some info for all the auras inside the group they can manually select needed tab.
