Welcome to the LE Community!
No. 1 is a nice QoL thing, to check what you are missing, but it also takes away some of the exploration aspect, which is already not very strong in LE.
No. 2
More detailed character sheetand stats is coming in the future. And mroe advanced minions stats will msot likely be part of this.
No. 3
This is a very hot discussed topic. There already were countless of threads about this.

TL:DR: It’s not a pure QoL Feature, but also impacts the whole looting experience.

No. 4
This has been adressed in one of the recent dev streams.
It might come in the future, but there are performance concerns and EHG is really carefuly with feature that could negatively impact your gaming experience, if you don’t use them properly.
