AI Usage Viewer

Changelog

v1.2.0 — 2026-10-03

You can now choose whether the numbers and bars show "% used" or "% left", at the top of the Display tab in Settings. The choice applies to both the panel and the text shown when you hover over the tray icon. Colors (green, yellow, red) and notifications are still based on % used either way. The notification threshold is now labeled "Notify threshold (% used)"
The weekly window now also shows the time left until it resets, in the form "3d 9h left". This also appears in compact view
Claude's weekly limit that applies only to the Fable model (the Fable weekly window) is now shown as a "Fable weekly" row below the weekly window. It appears only when the usage data includes this window. You can show or hide it with the "Fable weekly" item in display presets; it is not shown in presets that hide the weekly window
Fixed an issue where saving in Settings reset items not shown on the Settings screen (such as "show Codex's 5-hour window", changed directly in the settings file) back to their defaults
Fixed an issue where, when "Limit reached" and "Rate limited" appeared at the same time, "Limit reached" broke across two lines, or the badge ran past the right edge in English
Made the compact view window slightly wider so that text does not wrap in English

Fixed an issue where the detail panel would no longer appear when clicking the tray icon after changing the Windows display mode (e.g., "PC screen only" ⇔ "Extend"). If the panel was left off-screen or minimized, clicking the tray icon now brings it back onto a connected display

Fixed the layout and compact toggle buttons in the panel footer to show what they'll switch to, not the current state, so it's clear at a glance what pressing them will do
Clicking the × in the title bar no longer quits the app — it now minimizes the window to the tray (usage tracking keeps running). The separate minimize button has been removed, leaving a single × button. To quit, use "Quit" from the tray icon's menu

Moved the auto-update internals to a module shared by all six apps. How updates are checked, downloaded, and applied is unchanged, as is the tray and banner behavior

Migrated the release pipeline to a shared tool used by all six apps. No changes to app features or behavior

Updated the "View all changes" link in the update notification to the new distribution site URL, following the product site migration

Adapt to Codex's spec change where only the weekly limit remains. Usage is now shown and notified correctly even when only the weekly window is returned (previously the weekly window was mislabeled as the 5-hour window and notifications could be missed)
Usage windows absent from the response (such as the retired 5-hour window) are now automatically hidden from the panel, tray, and notifications
Added a config-file option (codex_five_hour_enabled, defaults to auto-detect) to toggle the 5-hour window display in case the 5-hour limit returns

Fixed reset times showing one minute earlier than the actual reset boundary
Fixed usage showing a "fetch error" right after the reset time (a transiently incomplete window no longer fails the whole fetch; the other window keeps displaying and the value self-heals on the next poll; applies to both Claude and Codex)
