What's new — SheetTimeline

Selected highlights. For the full technical changelog, see the product spec.

v2.5.0 · 2026-07-13

New "+ New task" button in the app header — add tasks that aren't in your spreadsheet yet without leaving SheetTimeline.
Added tasks show up immediately on the week board, day list, and timeline (dated ones on the calendar, undated ones in the Unscheduled panel).
On "End session & export", new tasks are appended as fresh rows at the bottom of your original .xlsx — existing rows and formulas stay untouched.
Task drawer gains a Remove button for tasks you added in-app, so you can drop one before exporting.
"All tasks" CSV/XLSX downloads and the Changes tray now include newly added tasks.

Launched publicly as SheetTimeline.
New marketing landing page at /; the app moved to /app (existing sessions carry over untouched).
Added privacy, terms, copyright, and this What's new page.
Anonymous visitor + session counters power the stats on the landing — no plan data is ever sent.

Added a backlog section to the spec covering future ideas (multi-plan library, accounts, monetization).

Round-trip export now preserves your plan's original status vocabulary and writes back to the mapped columns — even for plans without an ID column (row numbers can be used instead).

Stage strip: stages where every task is deferred no longer show a misleading 0%. "We are here" only marks stages with unfinished, non-deferred work.
Clicking a stage with no dated tasks now toasts to explain instead of silently doing nothing.

Generalized into a plan-agnostic viewer: only ID, Title, and Status are required.
Added a mapping wizard for custom column names and status vocabularies, plus saveable plan profiles.
Added workstream color overrides, app timezone setting, and a downloadable Excel template + sample dataset.
