Since you asked...

An icon pack I would love to see in a similar style is one containing action/command icons rather than inventory items. For example, "move", "chop", "mine", "transport", "store", "attack", "build", "craft", "steal", "open", "close", etc.

Some of those can be represented by inventory icons (e.g., an axe for chop, a pickaxe for mine, a sword for attack), but more generic commands such as "move unit" or "transport item" are difficult to convey visually without dedicated icons.

Some UI packs contain a few icons in this direction, but I am not aware of any packs with a good range of command/action icons.

Would be wonderful to see one :)
