Highlight ore tiles when placing miners.

The highlighting only shows up when an extraction machine is in your cursor.
Also activates for blueprints that contain extraction machines.

Automatically recognizes miners and resources that are added by mods.

No impact on performance while inactive, except for a small check when the item in your cursor changes.

configurability

You can change all options on the fly in mod options -> per-player settings.

You can change whether or not the highlight is drawn on ground level as well as the color scheme in the settings.

Limitations

• Due to technical limitations, the highlight can either be drawn on the ground level, which may be occluded by tall foliage or on top of everything, including the player.
• This mod currently does not support zoomed in map mode, but if someone can tell me where in the API I can find the camera position for zoomed in map mode I might add it.
• currently doesn't support multiplayer. (I seem to use some API calls that are disallowed for multiplayer and the mod logic is also not set-up for it)

If you would like to add resource colors for specific mods feel free to post color codes in the discussions and I'll add them when I have time.
Ideally with the in-game resource name and RGB in [0,255] format.
