Usage 0.5.0: Project usage gains a 'Month' toggle, and costs are no

Release notes

FEATURE

Project usage gains a 'Month' toggle, and costs are no longer zero

You can now view token usage across your projects for the last 30 days. The project usage panel has added a "Month" toggle (cycling through "Today" and "7 days"). Also, because Claude Code doesn't record the cost (costUSD), all projects previously showed $0.00; this is now fixed, and it calculates the correct cost. Additionally, the project usage icon has been resized to match the Claude Code and Codex icons. It's like an accounting book that used to only show this week's expenses, but now you can flip through the whole month, and every entry finally has a price tag.

FEATURE

Fallback pricing for the Opus model is more accurate when offline

When offline, the fallback price (the default rate used to estimate costs when the network is disconnected) for the Opus model has been corrected from $15/M to $5/M. This aligns it with LiteLLM's actual value. It's like going to your regular store when their network is down, and the owner quoting you a price from memory that's now much closer to the real cost.

FEATURE

Panel architecture completely overhauled, temporarily retiring old native panels and Antigravity tracking

To pave the way for upcoming new designs, the underlying architecture for all panels has been switched to HTML/CSS (drawing the interface using web technologies). Consequently, we've removed the Taiwan, Matrix, ECG, Minimal, and Sketch panels, which were written in legacy native code. At the same time, to avoid hardcoding credentials into the source code, Antigravity quota tracking has been temporarily removed until the feature can be redesigned. It's like gutting an old house to replace all the plumbing — some old furniture is temporarily unusable, but it's to make way for a much better renovation later.

Original changelog

Original changelogProject usage gains a 'Month' toggle, and costs are no longer zero

**Monthly range in project usage**: cycle through Today / 7 days / Month to view per-project token usage and cost over the last 30 days.
**Project usage cost now calculated correctly**: Claude Code's JSONL does not write a `costUSD` field, so all projects previously showed $0.00. Now uses the same `calculate_cost()` path as the "Today" footer total.
Project usage SVG icon resized to 30x30 to match Claude Code / Codex icons.

Original changelogFallback pricing for the Opus model is more accurate when offline

**Fallback Opus pricing corrected to $5/M**: the offline fallback price for Opus was $15/M; corrected to $5/M to match LiteLLM's actual value.
