Blobster 0.4 is an interaction and design update.

• One docked side pane for Inspect, Find, Query, and Compare replaces the floating panels, and a status line shows the selection path, copy actions, and file size.
• Edit values and keys in place in the tree, with one context menu for tree and table rows and column menus for rename, insert, hide, and delete.
• Press ? for a keyboard shortcut sheet.
• Open a body from a HAR or OpenAPI file, then return to the parent with the title breadcrumb, browser Back, or Alt+Left.
• Unsaved edits are protected: replacing an edited document asks first, and closing the tab warns.
• Large trees open level by level, with previews of collapsed containers.
• HAR previews gain a timing waterfall and pretty-printed bodies, and the JWT and FIX previews are tighter.
• Refined colours, focus states, and type in both light and dark themes.

Blobster 0.3 is a major local-first workbench update.

• Introduces a canvas-first interface that keeps the document central and presents controls only when they are relevant.
• Keeps edits synchronized across table, tree, and raw views, with first-click table editing and unified undo/redo.
• Adds Power Find with regular expressions, case sensitivity, whole-value matching, key/value scopes and previewable Replace All.
• Adds local JSONPath queries, structural comparison, inferred JSON Schema and authenticated URL refresh with credentials held only in memory.
• Expands HAR, OpenAPI, FIX, JWT, NDJSON/JSONL, Markdown, redaction and structured-copy workflows.
• Improves performance for everyday JSON documents and recovery from parser-worker failures.
• Improves compact and mobile layouts and fixes sticky table header alignment.

Blobster continues to process documents locally, without accounts, uploads, analytics, telemetry, cloud sync or public paste URLs.
