-
-1. **Calendario suscribible (ICS)**: una URL privada por persona con las fechas límite, los sprints y las releases de
-   sus proyectos, para Google Calendar, Outlook o Apple Calendar. La URL lleva un token propio (revocable), no el de
-   sesión.
-2. **Notificaciones push (Web Push)**: los avisos de la campana como aviso del sistema, aunque la pestaña esté
-   cerrada. Un _service worker_ en la web (que la deja instalable como PWA), «Activar avisos» en los ajustes de
-   notificaciones, las suscripciones de cada persona guardadas en la API y el envío con Web Push (claves VAPID, dos
-   variables nuevas). En iPhone solo con la web instalada en la pantalla de inicio (iOS 16.4+).
-3. **Campos personalizados por proyecto**: «Navegador», «Cliente», «Entorno»… de texto, número, fecha o lista de
-   opciones, definidos en Configuración; editables en la ficha, filtrables y como columna en la vista de lista.

-6. **Plantillas de proyecto**: crear un proyecto copiando de otro los estados, transiciones, tipos, áreas,
-   automatizaciones y etiquetas.
-7. **Sincronizar con issues de Gitea o GitHub**: hoy los commits y PR se enlazan a tickets; además, que un issue del
-   repositorio cree o actualice un ticket, y al revés.
-8. **Vistas guardadas en «Mi trabajo»**: montar la portada con filtros guardados de varios proyectos («Bugs críticos de

+   personalizados, automatizaciones y etiquetas.
+3. **Exportar e imprimir un sprint o una release**: un PDF con los tickets, su estado y las notas, para un cliente o
    para archivar.
-10. **Asistente en la web** (la base ya está en el MCP): resumir un ticket largo con sus comentarios; al crear un
-    ticket, sugerir tipo, prioridad y área y avisar si se parece a otro; redactar las notas de versión a partir del
-    borrador. Pendiente de decidir la clave de la API de Claude y su coste.
-11. **Avisos a Discord, Slack o Telegram**: los webhooks salientes mandan JSON en bruto, que esos chats no muestran
-    bien. Una integración por canal (o un formato por destino en los webhooks) mandaría mensajes ya legibles: «Ana
-    movió WEB-12 a En revisión», con enlace.
-12. **Conector de claude.ai**: el MCP necesitaría el flujo OAuth del protocolo, y Pireon publicar su metadata de
-    autorización y admitir el registro dinámico de clientes.
+
+Y en el panel del proyecto:
+
+4. **Sprint en curso**: días que quedan, puntos hechos y pendientes, y aviso si al ritmo actual no llega.
+5. **Tickets en riesgo**: vencidos, que vencen esta semana, bloqueados y atascados (días sin moverse en un estado en
+   curso), cada grupo con enlace a la lista filtrada.
+6. **Antigüedad de lo abierto**: cada ticket en curso por los días que lleva en su estado, con el umbral habitual del
+   proyecto (p85 del tiempo de ciclo).
+7. **Cuellos de botella**: días medios en cada estado y columnas por encima de su límite WIP.
+8. **Próximas releases con previsión**: progreso, fecha objetivo y fecha probable según el ritmo real (Monte Carlo),
+   con semáforo.
+9. **Qué ha cambiado desde tu última visita**: nuevos, cerrados, devueltos por QA y menciones.
+10. **Carga del equipo en puntos**: asignado frente a lo que cada persona suele cerrar por sprint, con aviso de
+    sobrecarga y sus bloqueados.
+11. **Salud del backlog**: sin estimar, sin área, sin asignar y sin tocar en 90 días, con enlace a la lista filtrada.
+12. **Calidad**: bugs abiertos por prioridad y su tendencia, devoluciones de QA por área y bugs abiertos en los 14 días
+    siguientes a cada release.
+13. **Desglose por campo personalizado**: tickets abiertos según un campo de opciones a elegir («bugs por
+    navegador»).
