Correction
The previous update hid text across the entire layer picker. We restored the original appearance of all 37 pre-existing controls and limited icon-only styling to Country capacity, Operating plants, Proposed power plants and Power construction. All 41 layer controls are retained.
Using the power controls
The four power controls use matching 32-pixel icons with hover names, accessible labels and search support. The other Infrastructure buttons keep their original icons and visible text. Refresh Watchtower to load the correction.
