3.10.0

Added

• Advanced spell filters - Filter spells by casting actions, listed defenses, targets, area shape and size, range, duration, and sustained casting in the shared sheet, character creation, and level planner spell picker (#112)
• Duration units - Enter duration bounds in seconds, rounds, minutes, hours, or days; switching units preserves the same limits

Improved

• Spell filter controls - Collapsible advanced filters include a clear button, aligned checkbox labels, and selection preservation while filtering

Text-based filters use listed English spell fields. Unknown values are excluded when numeric bounds are active; duration alternatives use the listed maximum. One round equals six seconds.
