v1.3.4-b1

New

• Mouse buttons bindable in the Key Viewer (LMB / RMB)
• Key rain corner radius, applied to its shadow too
• Key rain glow layer — size plus a tint that multiplies the rain color
• Preset editor regrouped into cards: Background, Border, Label Text, Count Text, Key Rain, Ghost Keys — each one toggleable

Improvements

• Key rebinding accepts every keyboard key (Menu, keypad, F13–F24, Print, Pause…)
• Escape leaves a pending rebind; clicking the armed key cancels it
• Rounded rain keeps its cap through the fade zone instead of squaring off early
• Long setting labels shrink to fit instead of overlapping their control
• Deleting a row or cell now asks for confirmation
• Update check no longer prompts on every launch on prerelease builds
