- Mining tab: sync s_selected_threads with actual thread count when idle thread scaling adjusts threads (solo via genproclimit, pool via threads_active), skipping sync during user drag - Auto-lock: bypass lock screen overlay when xmrig pool mining is active so the mining UI remains accessible - Import key dialog: add clipboard hover preview with transparent overlay on the input field, inline key type validation next to title (matching send tab paste button pattern), configurable via ui.toml
