+
+## Tasks
+
+### 1. Server health indicator on card `[ ]`
+- Call `/api/health` or ping the Immich server on load
+- Show green/red dot or badge on each server card
+- Auto-refresh periodically or on page load
+
+### 2. Album selector filter-by-name `[ ]`
+- Add search/filter input above the album checkbox list in tracker form
+- Filter albums by name as user types (case-insensitive)
+- Show match count
+
+### 3. Album last update time `[ ]`
+- Fetch `updatedAt` from Immich album API response
+- Display formatted last update time next to each album in the selector
+- Format relative ("2 hours ago") or absolute based on locale
+
+### 4. Review and improve message template engine `[ ]`
+- Current: simple Python `str.format()` style `{variable}` placeholders
+- Blueprint uses Jinja2 with `{% if %}`, `{% for %}`, `| join` filters
+- The TemplateConfig stores raw template strings
+- Review: should the server render templates using Jinja2 with the full
+  variable context? Currently `notifier.py` just does simple format()
+- Proposal: Switch to full Jinja2 rendering in notifier with all 40+
+  variables, conditional blocks, loops over assets, filters
+- Add template documentation/reference panel in the template-configs UI
+- Add a "variable reference" sidebar showing all available variables
+  with descriptions and example values
+
+### 5. Change user password `[ ]`
+- Add password change form to user profile (sidebar footer or /settings page)
+- Backend: `PUT /api/auth/password` (current_password + new_password)
+- Admin can also reset any user's password via /users page
