With a period of very limited playing time I would love to see a change in how Explorers return with their loot. It is in my opinion way too much clicking to receive the goods. What if TSO implemented a building for one of the levels that today do not receive anything special (After lvl 50 f.ex) where you get a explorer tavern or something like that. The tavern could "light up" when there is something to pick up.
In the same house you could upgrade the tavern, giving you features like sending all Explorers with the same skills out at the same time for the same search. Should be possible to make this a one click operation.
Further it should be possible to buff this building, so that the explorers return a tiny bit faster. Would be buffs the typical player saves for events or similar.
Anyway, love the game and I apologize not having read through all threads with "Explorer" in them. I admit - I don't have time for that. Sorry!
All the best
