I''l try to answer better about those plugins tomorrow evening (EU time) as I presumably have more time for this.
Well, kinda.
The blue text is for me to tell how much unused pools of reflection I have available. 10 pools = 100%
It also tries to calculate my effective XP/h after I close a rift.
Because I'm only interested in that number as it tell how effective my build is currently while doing rifts (not being idle or AFK).
Then I have an other plugin that shows possible pools of reflection locations I personally have found on the maps.
The yellow labels are for those. And white cross or yellow +-sign on minimap.
This is work in progress and not very useful on every map.
But there are few maps that can be checked quite efficiently if pools of reflection can be found there.
It just show that I'm alive (or killed X times). And how much free space I have in my inventory to collect loot.
After I die first time it GR I can take more risk as I have nothing to lose anymore

as I do mostly empowered GRs.
