User feedback:
> Awesome tool - wish I had this 3 months ago when I started my last run!
> Probably the only 2 suggestions I could think of would be

> For the power nodes: being able to show the radius (useful when planning placement of objects requiring high capacity power grid)
>
> I'd suggest changing the colour of the items under the wall category - it's a bit hard to differentiate them from items under the system category (both show as red on my screen... unless I've stuffed something up!)

> Great work though - like others I'd been muddling along with Excel :-)

## Feature requests (2 items)
### 1. Power node radius visualization
Show the effective radius/range of power nodes when placing or hovering over them. This helps plan optimal placement for high-capacity power grid coverage.
Implementation notes:
  • Power nodes have a defined radius in the game (need to extract from JAR or document)
  • Could show as a semi-transparent circle overlay when:
- Hovering over a placed power node
- Placing a new power node (preview mode)
  • Similar to how the game shows coverage areas
### 2. Wall category color contrast
Current Wall category color (
#3a4a5c
dark blue) appears too similar to System category (
#cc4444
red) for some users.
Current colors:
  • Wall:
    #3a4a5c
    (dark blue-gray)
  • System:
    #cc4444
    (red)
Possible fixes:
  • Adjust Wall to a more distinct color (lighter blue, or different hue entirely)
  • Add category icons/patterns in addition to color
  • Check for color blindness accessibility (red-green confusion is common)
