Thanks wzyas!  I particularly like your proposal #2 and #3:  #2: temporarily enlarge the minimap, e.g. double click on the minimap could open a window showing exclusively the map (enlarged), doule clicking again closes the sparate map windwo. #3: workes do not deplete berry bushes completely but leave a bit so they can re-generate. The same would apply to fishing boats.

It don't know if the rules allows it but here my request: Back in Empire Earth you could command units to auto-explore. It would be nice if we could do that. In Age of Mythology you can make the mini map bigger for a moment. It helps a lot. It would be cool if the workers don't deplete a fruit bush. They leave it with 1 hp and move to the next. Or become idle. Thanks for reading.  

Title screen -> Learn to Play -> Tips and Tricks or binaries/data/mods/public/maps/tutorials/   The chevrons above the units' heads signify (from single to triple) basic, advanced and elite rank; they go along with increasing attack and HP values and decreasing gathering speeds. (Since this site's search function is phenomenally terrible I don't know if there's a good overview somewhere.)  

Here on Medium AI (on Very Hard I don't outcompete economy early game, but I play quite intuitively, no videos or tips to know optimal build order, for now at least).

Totally agree:
