Changelog

Release history of Responsive Tester.

1.6.0 (2026-07-19)

Added an inspect tool: hovering a viewport shows how the element's declarations change across the site's breakpoints, with the values that currently apply highlighted.
Added inherited styles to the CSS editor: one section per ancestor, DevTools-style, with declarations that do not inherit dimmed and cascade losers struck through.
Added custom property values to the var() autocomplete in the CSS editor.
Added a license key prompt that opens alongside the checkout page, ready for the key on return.
Added a minimum application width; smaller windows scroll instead of squeezing the toolbar.
Updated the icon set to Phosphor.
Minor fixes.

Added a Manage Workspaces dialog: drag to reorder, rename, and delete workspaces in one place.
Added zoom presets: pick a level from 25% to 200% from the zoom readout.
Added a floating element label while editing: hovering a viewport shows the element's tag, id, and classes at the cursor.
Added rule creation from section headers in the CSS editor; new rules insert at the top of their section, matching their cascade position.
Improved breakpoint viewports: generated widths now account for min-width and max-width query direction, and paired breakpoints open on the desktop side.
Fixed hover highlights not following scrolled content in edit mode.

Added overridden indicators in the CSS editor: declarations that lose the cascade are struck through and show the winning rule on hover.
Added numeric stepping in the CSS editor: Up and Down arrows adjust numbers in values by 1, Shift by 10, Alt by 0.1.
Fixed pending edits from a previous selection applying to a newly selected element.

Added workspaces: save, rename, and switch between named viewport sets.
Added an option to reset viewports to the defaults.
Added touch emulation for touch-device viewports.
Added paste handling in the CSS editor: pasted CSS splits into individual declarations.
Improved keyboard flow in the CSS editor: Enter in a value commits it and starts a new declaration below.
Updated the extension icons.
Fixed the welcome page ignoring regional language variants (pt-BR, pt-PT).
