The Kanban sidebar panel's header '+' button (#kanbanNewTaskBtn) was
wired straight to createKanbanTask(), which reads the inline
#kanbanNewTaskTitle input and silently returns when empty. The inline
input lives below five rows of filters (search, assignee, tenant,
archived/mine toggles, stats, bulk-action bar) and is typically off-screen
on first panel open, so the header button looked dead — clicking it with
no title typed did nothing visible (no modal, no scroll, no focus shift,
no toast).
Now the header '+' opens #kanbanTaskModal — a centered overlay with the
same .kanban-modal-overlay shell the existing create-board modal uses,
so the two flows look and behave identically (centered card, dim
backdrop, ESC closes, click-on-backdrop closes). The modal exposes the
fields the backend already accepts at /api/kanban/tasks: Title, Description,
Status (Triage/Todo/Ready), Priority, Assignee (datalist suggestions from
the active board), Tenant (datalist).
UX details:
- Title is required; submit-with-empty shows a properly styled red error
- Title field auto-focuses on open
- ESC closes the modal; backdrop click closes; Enter on simple inputs
submits, Enter in the description textarea inserts a newline
- Submit POSTs only the fields the user filled in (no forced empty strings)
and auto-opens the new task's detail view
- Submit button disables while posting to prevent double-submit
- Inline quick-add (Enter on #kanbanNewTaskTitle) is preserved as a
power-user shortcut
Side effect: .kanban-modal-error styling improved (proper red alert with
border + tinted background) so the existing create-board modal benefits
from the same polish for free.
i18n: 11 new keys added across all 8 supported locales (en, ja, ru, es,
de, zh, pt, ko).
Tests: tests/test_kanban_ui_static.py::test_kanban_new_task_header_button_opens_modal
covers the modal markup, button wiring, ESC/Enter handling, datalist
population, submit behavior, and inline-quick-add fallthrough.
Verified end-to-end in the browser on an isolated test env (port 8789):
created a board from scratch, opened the modal via header '+',
submitted with title/description/status/priority/assignee/tenant filled in,
moved the task through statuses (Triage → Todo → Ready → Blocked → Archived),
added a comment, verified Cancel + ESC + backdrop-click all close cleanly,
verified validation error rendering, verified inline quick-add still works.
