On "Seam Cutter"

This is a niche tool solving a real problem that most image editors make needlessly painful: removing a vertical or horizontal band from the middle of a photo without flattening the whole composition. Willison's approach—sliding the two halves past each other instead of traditional crop-and-scale—is clever enough that it'll probably ship in mainstream software in two years, rebranded as "content-aware seam removal" or something. If you've ever had a photo that's almost perfect except for a distracting sign or person in the middle, you already know why this matters.
