v2.6.0

Features

• Screen lock with PIN & auto-lock (#235) — Lock MailFlow behind a 4–6 digit PIN, enforced on the server, with an optional auto-lock timer. Decoupled from your sign-in method, so it works even on SSO-only accounts that have no password.
• Drag-to-reorder filter rules (#253) — Reorder your filter rules by dragging them in Settings; the order is saved and rules run in sequence.
• GTD workflow (#250) — Opt-in Getting-Things-Done workflow with Todo / Watch / Delegated states backed by real IMAP folders, so your triage stays in sync with any IMAP client.
• New-release notifications (#261) — MailFlow now lets you know when a newer version is available. The check is server-side, cached, host-pinned, and can be turned off.
• Self-hosted fonts — All fonts (across every supported language/script) are now served locally. MailFlow no longer phones home to Google Fonts.
• Support development section — Ko-fi and GitHub Sponsors are now grouped under a single "Support development" heading in About.
• Named collapsed sidebar rows (#259) — Hovering a collapsed sidebar icon now shows its name.

Fixes

• Compose tab order (#266) — Pressing Tab after the Subject field now jumps straight to the message body instead of cycling through the formatting toolbar.
• AI Assistant settings (#258) — Opaque button surfaces, the Delete button is no longer cut off, and the configuration sits below the toggle.
• Sidebar collapse button (#254) — Corrected hover state, tooltip, and secondary-gray tone.
• Read/star sync — Read and starred state now stays consistent across devices.
