Welcome, you amazing community of The Amazing Game, especially you Wube Software lads!
So I haven't been following the amazing game for a year or so; only downloading latest update every few months but not the forum, so some suggestions are already or to some extent implemented, at least in some mod.
TL;DR
requester chests should indicate (by light on them like miners) of how much there is of requested items (I don't use logistic robobots much so I don't know what metric to base needed demand as)What?
when you hover over a requester chest (or any filtering entity like storage chests filters), it should show the available logistic content of requested/filtered items.In simple words, if a requester chest asks for 50 copper, it should display how great the logistic network the chest is part of, is doing on the copper department. OFC as humans we know it's either we're lacking ore or not smelting enough, but basic diagnostics mods can manage would be like if there's enough copper plates in the network should be relatively easy to implement, I think; It's simply the entire list of logistics filtered through the requests of such entity. The display may be on chest GUI only, or a similar green, yellow and red light like it's with miners an belts.
