README

Signature Randomizer is a Roundcube plugin that allows each identity to have multiple signatures.
Each signature can be weighted, randomized, and managed through a built-in UI.

• 🎲 Randomly insert a signature when composing an email.
• ⚖️ Assign weights to control how often each variant is chosen.
• 🖊️ Manage variants per identity in Roundcube settings.
• 📤 Import / export signature sets as JSON.
• 🔀 Shuffle or preview directly from the toolbar.

Features

• Weighted signatures: Increase or decrease the probability of each variant being chosen.
• Per-identity management: Each Roundcube identity can have its own set of variants.
• UI integration: Manages signatures directly in the Roundcube Identities settings.
• AJAX actions: Add, save, duplicate, delete, reorder variants seamlessly.
• Composing integration: Works in both compose and reply modes.
• Import/Export: JSON-based backup and restore of signatures.
