there is also a bug in the display if you hover over the green tick, it sometimes displays the wrong difficulty -see screenie (actual diff was 106.xx)
no bug
correct behavior
it show the diff of last block
no matter if POW or POS
if u see a low diff like in urs screenshot it was a POS block
in console the command getdifficulty show u actual POW/POS difficulty
ahhhh thanks for that i thought it was kinda weird!
yw
regarding ur original question
i did think a bit more and in my opinion its a specific information
that only is interesting for miners
the information is visible at any mining pool
or via console command
its no information interesting for mainstream wallet users
(there is a lot POS related info every owner of DMD would see much more
than POW infos because everyone who own DMD is a POS minter....)
i know its hard to believe but more and more
the majority of cryptocoin wallet users isnt active miners
we leave that stage of crypto
its the same as with gold
so many people care for gold
but just a tiny little bit of them care about where and how it is mined
what are the best mining engines
how hard the stone is and if its to expect the stone after that one will be even harder....
i think a little tool sending api commands to wallet and read and display information that fit ur needs is the better solution
and everyone is free to create such tools
when we run out of other work to do we could think about do it ourself
but for now we have so many projects going on that give value to more than just the miner crowd
I know how to handle her LOL
