How things stand right now, certainly there has to be a line stating "Regenerates: 1 Food / 5 seconds" (seemed that rate, and trying to emulate correct nomenclature).

Shipsheds should be rotated 90°, that way you can easily make them longer in the correct direction to fit the ships inside. Vanilla follows this idea, but it's also wrong there, because the game does this:   When it should be like this (more efficient): These are Athenian structures, built monumentally, most other Greeks (like the Thebans, who were not good at sea) would use impermanent timber shipsheds.

Maybe we should enhance the tooltip of fruits (bushes, trees ...): https://gitea.wildfiregames.com/0ad/0ad/src/commit/2cc0cf457a766000e6372355e8c2b97e824bb962/binaries/data/mods/public/simulation/templates/template_gaia_fruit.xml#L9 Any ideas?

Gosh, I never noticed this! They do, just checked. That has to be one of the reasons why I was recommended time ago to distribute the gatherers among different berries, one ends extracting more food this way. I can't find something I proposed time ago: I wouldn't make the berry tree disappear when done, but leave an empty bush that can provide a little wood. Either one chops them for wood, or leaves them for food. Now I'd add that one could then make regeneration a bit different: not slow and continuous, but faster and at certain times, depending on the tree type.
